I do think too many games are over-using the Wii controls at the moment. Mario's use of it for the rolling/manta surfing mini-games is excellent, and even the waggle is fairly well done, but the pointy-shooty addition feels irrelevant. Whereas Resident Evil 4 used said pointy-shooty brilliantly, but added a largely annoying WAGGLE NOW GOGO! feature to the cut scene bits. And Zelda shouldn't have used any Wii features outside of the fishing really.
It's definitely more down to game design decisions that's making it like this so far though, as the Wii controls themselves haven't actually been bad. The designers simply need to realise that their games don't have to use all of the Wiimote options, when only a few are really needed.
Speaking of which, of all the features of the Wii, I actually think the two-handed controller idea is ace too. Resting both hands more naturally (when I was playing Zelda mainly) was great for utter laziness.
EDIT: Oh, and of course, to actually address the OP: I'm not sure there's much need to really. The Wii is great fun, but there's absolutely nothing wrong with the standard controller either. The 360 controller is ace, and the console still sells well enough.
