Once products ship and new planning/development cycles begin at Microsoft, management changes often happen. Plus, at the end of each calendar year (and also many times at the mid-year point), Microsoft often instigates reorgs, sometimes within single business units, and other times across business units.
Its too early to assess either Windows 8 or RT as either success or failure. Sinofsky moved to Windows because the development process that led to Vista was broken. He fixed the unit at the price of a lot of discord but he leaves behind a unit that is working smoothly which makes it a great time to get out while the getting is good. As a 20-year veteran of MS he is already nicely covered for whatever he wants to do next.
(Most likely: a start-up doing software for Windows. Or maybe he'll go to Apple. They have a vacancy.
