Why can't Nintendo just sue Sony for imitation?

answer is simple: they didn't invent motion controllers....just because the shape is similar doesn't mean it uses the same tech and as far as I have seen the Move is much more responsive as well...so no they can't sue Sony and if they do they will lose easily.....

Huh? Much more responsive than what? Wii Motion Plus is 1x1, you can't have something better than 1x1. The "Move" is similar to the Motion Plus or worse, but it's impossible to be more responsive.

Ok so I HAVE played Wii games...plenty of times...but there are times the moment I move eve nthe slightest away from the range the whole game messes up....we already got testimony on how the camera can guess and act acording to sudden changes in movement in such situations...Wii just can't do that
