They can certainly be copied successfully, I don't disagree with that. Microsoft can and will enter the new market. What I disagree with was your assertion that proper software support isn't needed. I think the evidence goes against that. Even if you exclude Wii Sports Wii's attach rate is nearly the same as PS3, though both are below X360. And then you look at what has sold, on the million list yes there are mini-games that did well(with many more that fell flat) but there are also games like SSB:B, Super Mario Galaxy, Zelda: TP etc. among others that have sold very very well in their own right. These are top sellers, so I don't think you can claim they're unimportant.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
