With the new Wii and their game development kit, this could be an incredible opportunity for learning. Nintendo has done a remarkable job already with mental fitness in the DS. The ceiling for the Wii is incredible. The ability to work in 3 dimensions, combined with tactile feedback could provide for a great learning experience.
Anyone who has spent more than 5 minutes will admit that this is not just another game system. Gamers and non-gamers alike love the new experience the Wii provides.
Hopefully the learning community can jump on this new development kit and build something special to help take human performance to the next level.
