Next generation Wii planned

The Nintendo Wii has been a great success for the company, but never to sit back and pat themselves on the back for long time are the people at Nintendo already working on the next version of the popular games console.

It has been said that people do not buy consoles just for the sake of having a machine sitting there; the idea is that they want to play games and this can only be done through the games console.
The most memorable thing able the Wii was not it shape or even the games, because they come later.

The thing that has interested people even those who do not use a Wii is the controller; they took the traditional controller and completely gave it a new lease of life.

The question that should be on the tip of out tongues is how can they top that?
