Nintendo don't like to repeat themselves, Look at all the consoles before. The NES, SNES, Nintendo 64, Gamecube and the Wii. They were all different in design. I reckon the next one will have motion controls but it won't be so emphasized this time, the 3DS is basically Nintendo's attempt at reclaiming a more gamer centric audience and it wouldn't make to bring out something for a different audience as the main console since the portables and consoles of Nintendo have always been linked in someway.

The next Nintendo console won't focus as much on the Casual audience, that's one thing we can count on given the 3DS. However this article's referring to a Wii upgrade rather then the next generation. It'll probably be the Wii HD that's so often rumoured, as for it being destined to fail, well look at the DS's upgrades they've all sold very well and the wii's core audience is the same.
