Xbox department head Robbie Bach and "Chief Experience Officer" J Allard (considered by some to be the father of the Xbox) will be ending employment with Microsoft this fall, according to an internal memo sent from company head Steve Ballmer and acquired by TechFlash. Allard will stay on in some form, serving as an "advisor" to Ballmer, though Bach will be outright leaving after nearly 22 years with Microsoft.

"For the past 22 years, Robbie has personified creativity, innovation and drive. With this spirit, he has led a division passionately devoted to making Microsoft successful in interactive entertainment and mobility," Ballmer said of Bach's departure in the company's official release. And Bach expanded on his departure, saying, "I'm at the time in my life where I want to dedicate more time to my family and my nonprofit work, including my work with the Boys & Girls Clubs of America."

The shakeup additionally sees current senior VP of Interactive Entertainment Don Mattrick and senior VP of Mobile Communication Andy Lees taking new positions, reporting directly to Ballmer himself, while David Treadwell will now head the core technology group inside the Interactive Entertainment division at Microsoft. Oh, and as you might expect, no mention was made of the Courier in any of this.
