ive got a wii in the last few days and the endless slashing of the wiimote can get irratating in Twilight Princess, and now a controllerless version that MS are pushing is going to be released, i just cant see it doing well on the 360 as its already established its audience, who from my point of view are not interested in this kind of stuff.
But nevertheless, new entrants into the market may find it new/unique and want to have a go which could cause it to catch on in even a hardcore gamers apartment.
