Dont understand why you are confused. People want games to play not novelty swinging bats and and mindlessly pressing buttons acting as if its an instrument. Sony's eyetoy suffered from the problem- the novelty wore out. You have to give good reasons for people to enjoy these new peripherals and to go out and buy them. Waving stuff around can be fun given the right context, the E3 conference showed a brilliant peripheral but nothing mildly interesting to use it on.
Its like Ferrari announcing a new brilliant engine but no body of a car to go with it. It would be pointless!
