Yesterday it was rumored and then confirmed that Microsoft's Xbox One chief Don Mattrick had decided to leave the company to become CEO of Zynga. Many gamers angry about the limitations imposed by the Xbox One, which Microsoft later backtracked on and removed, will hold Mattrick to blame. With him now gone, what Microsoft needs is a replacement chief who knows games well and at least has the respect of gamers from their past achievements. Without that, the Xbox One could continue to lose ground to the PS4. Whether Microsoft realizes that or not, it seems they aren't in any rush to hire someone new or promote an existing Xbox team member. In fact, Don Mattrick is being replaced, but not by a games person. Instead, Steve Ballmer will be taking on his role and handling all communication with the rest of the Xbox management team. It's unclear if Ballmer's takeover of the Xbox division is a temporary measure or whether he sees himself as the best man for the job long-term.
