No, you read that correctly. Effective July 30, Peter will be stepping down from his position as Senior President of IEB at Microsoft. Moore has decided to return to his family in Northern California, where they lived until he took he position at MS. He'll be remaining on board to assist with the transition for his successor, Don Mattick. 

Update: In case you just tuned in — we've found out the TRUE reason why Peter left Microsoft. Hm… makes you wonder where some of Nintendo of America's top execs have gone off to, eh?

"“Peter has contributed enormously to the games business since joining Microsoft in 2003 and we are sad to see him go,” said Robbie Bach, president of Entertainment and Devices Division at Microsoft. “Since that time, he presided over the global launch of the Xbox 360™, spearheaded a revitalized and rebranded Games for Windows business, and helped steer the console’s ascent."

Mattrick will take over as the senior vice president of IEB at Microsoft, effective July 30. Mattrick was the founder of Distinctive Software Inc., which operated as a private company from 1982 until its merger with EA in 1991. Mattrick held various senior positions within EA, most recently as president of Worldwide Studios, until his resignation in February 2006. In February 2007, Mattrick began working with the Entertainment and Devices Division at Microsoft as an external advisor.

Good luck Peter, you've made a huge asset to MS and wish you the best! Hopefully EA will reach some new strides of innovation with his addition.
