sounds like it should be on the PSMove since you mentioned motion camera wiimote also the facebook part. I think they should use a disc less update system instead of releasing a new one with minor changes. There isn't much you can do with it except increase the song selection and add more preference options. I'm guessing it will face the same problems as rockband or guitar hero.
What I want from a game.
Gameplay > Story > Content > Graphics
Visual Style > Graphics
Smooth Camera, Intuitive Controls
Friction! When everything feels right!
