You must watch the video from Johnny Lee in which he demonstrates the effects that are possible with the Wii remote and using it for head tracking.  It can be found at http://www.youtube.com/watch?v=Jd3-eiid-Uw

 Now that you have seen what is possible with his demonstration, imagine for a moment a first person shooter where you can look around the corner by moving your head, or a motorcycle / snowmobile / or ATV racing game where you have to lean as you corner while traveling through a 3-D world, or skiing / snowboarding down your favorite run in Snowbird, Alta, Park City or Lake Tahoe.  Wii tennis where the ball flies at you in 3-D.  Network 2 Wii’s together and have a very real boxing match.

 I second Johnny’s challenge to all Wii developers, I want to see some cool games.
