The next Xbox will be revealed on May 21st, Microsoft has announced.
According to an invite received by Shacknews (above), "Don Mattrick and the Xbox team" will present a "special unveiling" on Microsoft's Redmond campus at 10AM PT (click to see your local time). Major Nelson promises a "live global stream that will be available on Xbox.com, Xbox LIVE and broadcast on Spike TV if you are in the US or Canada."
The date aligns with a rumored leak, which makes us wonder: how many of these next Xbox rumors are true?
The next Xbox is rumored to switch to an x86 architecture powered by AMD, not unlike PlayStation 4. Early rumors suggested that the next Xbox will use slower memory, and will be very slightly outpaced by Sony's next-gen hardware. The new system will also use updated controllers.
Microsoft has gone on record to say that their next system will be more entertainment focused, with the company placing a large emphasis on non-gaming content. Controversially, early reports suggest that not only will the next Xbox include (and require) an updated Kinect peripheral, but it will also require an always-on internet connection. The last point is perhaps the most sensitive issue amongst gamers, and gamers will be hungry to get Microsoft's official stance during their May event.
