Microsoft unveils Xbox One next-generation console
Microsoft has unveiled the Xbox One which will go on sale later this year.
The next-generation console was shown off alongside a new Kinect sensor and a redesigned gamepad.
The US firm described the voice and gesture-controlled machine as an "all-in-one" system offering games, live TV, movies and music.
The firm's Entertainment and Devices Division accounted for $9.6bn (£6.3bn) worth of sales in Microsoft's last financial year.
That only represented about 13% of its total revenue for the period - but one analyst said the importance of this launch should not be underestimated.
"Microsoft is very strong in business software and the enterprise cloud business, but its consumer businesses are facing tremendous challenges: PCs are declining rapidly and Windows Phone handsets have only a fraction of the market shares of rivals," said Jia Wu from consultants Strategy Analytics.
"Xbox represents Microsoft's core strategy in the consumer entertainment market, especially after it sold its Mediaroom video distribution business to Ericsson earlier this year.
"This is also the unique asset which Microsoft has that can differentiate itself from Apple, Google and several of the other large tech companies."
Microsoft's decision to show off its new hardware in the opening minutes of its presentation sharply contrasted with Sony's PlayStation 4 press conference in February when the Japanese company decided not to reveal the look of its machine - a move that was mocked by some commentators.
Despite earlier speculation, Microsoft's machine does not require an always-on internet connection and will run second-hand games - the firm told the BBC it would provide more details about this "in the coming weeks".New features
The Xbox One sees Microsoft add a Blu-ray drive and Skype functionality to its console, incorporate vibrating feedback into its gamepad's triggers, and upgrade the Kinect camera's sensor to 1080p high definition resolution.
It's about far more than games - that was the key message from Microsoft's Xbox One event.
In its eagerness to stake its claim to be a major force in the living room it was nearly half an hour before Microsoft executives got down to showing off the console's prowess as a games machines.
Instead they gave us quite an impressive demo of its other capabilities, from calling up live TV to making a Skype video call.
Unlike Sony, whose PlayStation 4 event earlier this year proved something of a tease, they showed us a box - albeit quite a chunky inelegant one - within the first five minutes.
But in its determination to build the "all-in-one entertainment system for your living room" Microsoft is taking a risk.
It's the hardcore gamers who queue up for new consoles - and if my Twitter stream is anything to go by, many were not impressed.
"Terrible stuff," wrote one.
"My guess is that the Xbox reveal will be universally slated."
Microsoft, however, having once bet that the PC would become the centre of home entertainment, now needs the Xbox to take on that role.
For Steve Ballmer and his company, this is no game - it's a battle for the future.
It said the new Kinect would be better at analysing body movements, allowing users to more accurately control games characters and navigate other entertainment options.
"When you're exercising, it can read your heartbeat," claimed the firm.
New tools will also allow users to record and edit gameplay so clips can be easily uploaded to the web.
EA Sports was first to announce new titles for the machine revealing Fifa 14, Madden NFL 25, NBA Live 14 and the fighting game UFC would all launch on the platform within the next 12 months using a new games engine called Ignite.
It said the new machine allowed it to carry out four times as many calculations a second as the Xbox 360 and 10 times more "animation depth and detail".
Microsoft Studios also revealed that Forza Motorsports 5 - the latest in its own racing car franchise - would be available when the console launched.
The division added that it planned to release 15 games within the console's first year, eight of which would be new franchises.
Activision also provided a first look at the next title in its Call of Duty series - Ghosts. It will use a new games engine to take advantage of the Xbox One's improved graphics capabilities, offering more detailed textures for human skin and other features. The title will also be released on rival platforms.
French publisher Ubisoft was not part of the launch, but took the opportunity to announce that two games in development - Watch Dogs and Assassin's Creed IV Black Flag - would be available for the Xbox One before the end of 2013.
The company's chief executive, Yves Guillemot, said he was excited by the opportunities offered by the machine's improved specifications.
"We believe it will reinvigorate the industry," he told the BBC.
"There's a huge step up in graphics and there's a big step up in terms of memory as well.
"It will take time to take full advantage of the machines because we'll have to learn how to best optimise the technology - but even from the beginning you will see a huge difference between a game on the two different generations."Entertainment epicentre
Much of the presentation was dedicated to the console's non-gaming features including its ability to make video calls; trigger live TV and online movies by voice command; and run several progams simultaneously without any apparent drop-off in performance.
Time was also given to promote an upcoming live-action television series based on Microsoft's Halo games franchise which movie director Steven Spielberg is working on. The firm said tie-in interactive content would be offered exclusively to the Xbox One.
"Where Nintendo's approach to next-gen gaming seems to ignore the need to share time with television and other forms of entertainment, and Sony's approach seems willing to share the space, Microsoft's vision is to so blur the line between different forms of entertainment that switching from game to television or movie watching will be as simply as flipping between television channels," said Brian Crecente, news editor at games site Polygon.
"More importantly, it is lining up to make its system the one through which all entertainment happens. If it manages to pull it off, the Xbox One could become the one jumping off point for all forms of entertainment."
News of a five-year deal with the US's National Football League - which will allow sports fans to call up statistics, video replays and information about what live events mean for their fantasy teams - may also appeal to Microsoft's domestic audience.
However, it did not discuss whether it was pursuing similar tie-ups for consumers overseas.
Video gamer's view
The Xbox One's name points to how it's the embodiment of Microsoft's strategies for trying to secure dominance in the living room spaces of the US and the world beyond.
For more than a year, the firm has been loading up Xbox's online services with apps that let you watch video content from a plethora of providers.
Now, it's shown the next stage of that ambition, with live TV playing directly on the console via a cable subscription or satellite set-top box.
The worry had been that Microsoft's designs on TV content would mean it gave short shrift to actual video games.
It did show games today, but it needs many more to convince its hardcore audience that the titles are not just a stepping stone to it conquering the living room.
Lots of other crucial details still need to be divulged, not least how aggressive it will be about the launch price.
Microsoft is planning to launch its new console at a time when many video games makers are trying to reduce costs.
Electronic Arts, Square Enix and Activision Blizzard are among firms which have announced layoffs over the past couple of months.
But the updated machines may put the companies under fresh strain.
Games engine developer Epic has warned that if studios want to take full advantage of the advances in graphics power that will be available, then their design costs could be double what they were when the Xbox 360 and PS3 launched.
"The additional rendering capabilities of these consoles will demand larger budgets for the marquee high-end games," said Lewis Ward, video games analyst at tech research firm IDC.
"That creates a risky proposition for developers.
"But the costs are going to be mitigated to an extent - studios have said it will be easier to make games on next-gen platforms because they're going to be closer to the development environments that are common on the PC side."
Mr Ward was referring to the fact that Microsoft has decided to power its machine with an eight-core x86-based CPU (central processing unit) made by AMD rather than continue with IBM's PowerPC technology. The move means its console will run off a chip that is similar to those found in most PCs.
Sony has also opted to switch from its proprietary Cell processor tech to the x86 architecture meaning, in theory, it should be easier to port a title across different platforms.
However, the move means neither of the two new consoles will be backwards compatible with the former generation's catalogue of games.
Both Microsoft and Sony plan follow-up "keynote" announcements at the E3 trade show in Los Angeles on 10 June.
Nintendo launched its next-generation console, the Wii U, last year and has said it will not host a major press conference at the event.
