I just wanted to know if you wanna see any add-on hardware you would like to see.
For starters I want
1. To see a strap-on "LegMote" that you can wrap on your ankle which can be used to play some serious Martial Arts games. Maybe useful for tennis as well. this way you can REALLY move around.
2. This is a wild one... WiiSuit. A full body sensor suit. Imagine that!
