Wii U a transitional platform?

[JEMC]

While I agree with most of the things Peter Moore said, nothing better than 1080p (for TVs) or reaching a point of diminishing returns, I have to disagree with him when he says that it will be about the interface.

If Wii has taught us something is that:
1-If a new interface doesn't always work with all kind of games, and the wiimote hardly worked with racing or fighting games, developers won't use it.
2-The power of a console matters. You may have the best interface, but if developers can't bring their games to your console using the same basic assets (graphics engine, textures, etc) they will not bother.
