as a ps3 owner....
... its crap if you ask me, motion control works for the wii in my opinion but the 360 and ps3 are more of a serious gamers console while i consider the Wii to be more of a party/social console i just cant see it taking off on the ps3 if it ever goes into production.
im far too happy lounging in my massive chair in front of the TV shooting nazis down over kent with a pad anyway
plus its more satisfying throwing a pad when you loose
