I mainly want the thing for The Show 2012 (since it won’t be out for the PC and MLB 2K12 sucks donkeys and I’ll be sending it back), but is it better or comparable to the Wii? Are the games designed for it any good?
MLB The Show is a Sony Playstation exclusive.
RRR-I don’t need Gran Turismo 5 because I already have plenty of PC racing games. Are there any Kinect-type devices for the PS3? Thanks for the heads-up in any event. 
Yup, the Playstation Move. It’s not voice activated, and is more Wii-like than the Kinect (because you need an actual controller). I’ve just used it once, so can’t tell you much more.
