I don't know if it will sell as well or not, it could sell better for all I know. The Wii Two will be released as an answer to any attempt to take Nintendo's market, which is likely to come from Microsoft.
One thing is for sure: it will have full backwards compatibility. It probably will look very similar to Wii. They may even drop the original Wii models and introduce a model that is still at a mass market price, but simply functions as an improved Wii that can also play something new(whether that's in HD, or simply an even more improved control system).
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
