Look to the DS for that answer, yushire. The initial DS offerings were largely along the same lines as the initial Wii offerings have been: a bunch of great Nintendo games, a handful of good third-party games, and a lot of games that nobody wanted. That changed as developers learned to use the DS stylus controls in new and innovative ways, and (in the case of more traditional games) learned to not let the stylus be a mandatory element when it made no sense.
The Wii will reach those stages too. The "old-gen" developers who cannot adapt to the Wii's new controls will find ways to use its non-motion-control ones. You'll probably see a lot of those developers adding Classic Controller and GameCube controller support. The "new-gen" developers will get their bearings on how the Wiimote really works, and start putting out games that will even make Nintendo marvel at the innovative use. As ever, things don't just happen. It will take some time yet for these changes to come about.
