I'd hate to be the one in charge of that type of transition. I think you can say one good thing about all the different UI changes manufacturers make on top of Android, it let Google start clean with 3.0 and 4.0 without changing it on a bunch of current users. After all, not many use the default theme anyway. :( I think it looks the best, but try telling Samsung and HTC that. At least they all need to include the Holo theme from now on so apps can choose to use it if they want to.
