I've heard rumour that MS has already axed any radical changes to the UX. In other words, the Windows 95 interface will continue. Windows needs a vision, right now it looks like it is being run by a Dilbert comic. If it wasn't for Bill, we would be using Program Manager and File Manager with Aero graphics. Sad. Get rid of the Gorilla.
Didn't you see the "radical new WP7-inspired UI"? (Which will presumably have to revert to a normal Windows desktop as soon as you actually launch an app.)
