To be honest... that's what the Wii is there for. To provide a different method of gaming, and to aim for a different audience than other consoles. I can hardly see them giving players the choice between a Wii remote or a standard controller. They do it for some games, like SSBB, but you don't often get games like that.
The Wii now is used by families that like to do stuff together. And the majority of games released for the Wii are designed to be played by large groups of people, and I can't see it changing.
I'd like for the Wii to be a console that uses normal controllers, but as Venks said, it's basically a GameCube++, and if they focused more on gamepads, it wouldn't interest anyone enough, because it would simply be a rehash of the previous console.
