Apparently today, Nintendo realized the market out there for Children and Adults who are seeking to shed some pounds by creating Wii Fit. Wii Fit set contains a step board platform that measures your balance, and even your body mass. The board itself is wireless using Bluetooth like all the other standard Wiimotes use. It also seems like it could be used for a possible DDR game in the future. It’s due for sometime later this year (probably Q4 around Christmas time).
I wish I had this when I was young ;)
