Is Moore the fall guy?

The news that Peter Moore, corporate vice president of Microsoft's interactive entertainment business - aka Xbox 360 boss - has resigned can be taken in two ways. Yes it could be entirely down to personal reasons and his new role - heading up EA Sports - is hardly a step down. But the timing is suspiciously convenient too. Recent sales target failures plus the repair bill fiasco won't have gone unnoticed at the highest levels of Microsoft. Whatever the reason I'll be sad to see Moore go. I've spoken to him on a number of occasions and found him a refreshingly open exec without the myopic outlook often displayed by senior games industry figures. Just another suit moving on then or is Moore's departure the first sign of cracks in the 360 masterplan?
