I have VERY high hopes for this and want it soon. I don't know what it could be used for though as the nunchuck wouldn't be able to be used so how can you move? Maybe it would be a point and click game to move the character like in Animal Crossing or something. Since Pikmin is my favorite franchise I would like to see Pikmin 3 use the vitality sensor.(Highly doubt it!) The bigest problem would be how to move around Olimar with no nunchuck. The Vitality Sensor could be used to rumble when you are near treasure but then again couldn't they just make the Wii Remote rumble instead? Maybe...
I don't know but I want it!
