It’s hard to call the Xbox 360 anything but a success, but having missed some sales numbers, ringing up an extra unexpected $1b on the corporate card because of warranty issues, and still generally failing to make a profit, it looks like Peter Moore, who we just sat down with a few days ago, has stepped down from his embattled position as the ringleader of Microsoft’s Xbox group. Successor to his role is Don Mattrick, who is taking over not just Peter’s position as VP of Microsoft’s Interactive Entertainment Business, but leading the group (including Games for Windows) entirely. Moore’s new job? Prez of EA Sports, down in the SF bay area. Take THAT, Microsoft.
