The problem with motion controls is that they're mostly being shoehorned into existing genres. I also think you guys (along with most developers) are playing down the advantage of the pointer - that thing was potentially more useful than the motion control.
If you track down the original TGS 2005 video revealing the Wii Remote, none of the people in it are playing games in established popular genres. They're playing games about fishing, cooking, dentistry, orchestra. One kid in that video was playing a shooter. I think Nintendo really wanted developers to go back to the drawing board with their game ideas around motion control, and most of them didn't.
That said, a lot of the best stuff on the Wii revolved around the pointer, not the motion control. Trauma Center is an excellent example. That Silent Hill game almost amounted to a classic point n' click adventure with full 3D movement. I also heard a lot of praise for the Wii versions of the Pro Evolution Soccer games and how they used the pointer for more fluid team control. I still wonder why no one at least tried to make an RTS for the Wii.
