What i think the Wiimote has over the PS Move (if it end up more precise)

[Gaffer]

I have yet to be convinced that it'll sell well (I myself have no intention of buying one) or that it will be any way better than a wiimote with WM+ (so far, I'm yet to be convinced).

If it does all of the above, it still has years of nintendo GAMES to try and better too - remember, sony are effectively starting out from the same position as nintendo did in 2006...they've got 4years of catch up to do.
