Motion Controls should slow down the action.

Motion controls should be used as an enhancement. I think the best way to use them would be in tandem with a controller to make a deeper experience. Take MGS4 for example. You control snake in the usual manner but to switch on solid eye you would do the same little flip down movement over your eye that snake does when he puts it on. Little stuff like that could make a game cooler.

A way I picture for almost total motion control (still believe in things like nunchuck for movement) would be something like Dynasty Warriros, but fighting the monsters one on one. This way, you don't have to just mash buttons or flail the controls to take them down.

Then make it in slow motion, just not too slow. This would not only avoid repetitive motions, but also allow for precision, since you have the time to make sure each slice is precise. So if you want to go for a demon skeleton's femur, you don't have to just make a slice and hope it's accurate before you have to block the skeleton's following rapid fire slicing a split second later.
