If you want playstation move, then play SOCOM 4 or Killzone 3 when they come out.
The problem with Crysis 2 is that the Move is not standard. Since Crytek is developing and innovating on the PC and then porting it to the console versions, there won't be any Move support. If it can't be innovated on the PC, Crytek won't waste the time to innovate it for the PS3. The development team has to draw the line somewhere since its multiplatform.

Since Killzone 3 and SOCOM 4 will be exclusive to the PS3, their dev. teams have more time to put PS3 exclusive innovations into their games.
