UPDATE #2: Microsoft CEO Steve Ballmer has responded to Mattrick's departure in an e-mail sent to all affected Microsoft employees and later published on the company blog.
"This is a great opportunity for Don, and I wish him success," Ballmer said.
"Since joining IEB [Interactive Business Group] more than six years ago, Don and his team have accomplished much. Xbox Live members grew from 6 million to 48 million. Xbox 360 became the No. one selling console in North America the past two years. We introduced Kinect and have sold more than 24 million sensors. We released fantastic games, and, most importantly, we expanded Xbox to go beyond great gaming to deliver all the entertainment people want - sports, music, movies, live television and much more."
