Alas, this list is coming to an end I guess. Don't forget Kirby: Dream Collection and Inazuma Eleven Strikers (PAL) are coming out as well as Epic Mickey 2 and yes... Just Dance 4. All probably deserve to be listed.
Some other suggestions to add:
Sam & Max Season Two; Beyond Time and Space
Secret Files: Tunguska
Secret Files 2: Puritas Cordis (PAL)
Back to the Future
I'm surprised to see no one ever recommended Big Brain Academy but it should be there under puzzle.
We Ski & Snowboard (We Ski) - fun casual title
and one of Wii's most overlooked games that is developing a serious cult following:
Fishing Resort - the deepest and best fishing game on any system.
