Actually, it occurs to me that most people don't really get what the Wii's sub-market is. Not surprising, there are few developers who have even figured it out. So I'll outline it.
The Wii's sub-market is a combination of intuitiveness, immersion, interface, convenience, and pick-up-and-play appeal. The complexities of getting into the game are alleviated by controls that make sense without having to consult the manual. The gameplay feels more satisfying because you're actually doing what your on-screen character is doing. The interface doesn't try to overload you with options and extras. The games don't leave you feeling like you have to put aside half a week to finish them. And you won't have any qualms about just popping the game in for a quick 15 minutes at any time.
You may have noticed that most of this seems to have nothing to do with the system itself. But there's the rub: all of those pieces are necessary to effectively compete against Nintendo in the new market. If you don't have controls appropriate to the goal, it doesn't matter how well you fit the rest of the criteria. Similarly, the controls alone won't cut it. Even the Wii's non-game interface reflects all of those values. Nobody is going to scratch their heads in confusion at the Wii Menu, but I've seen a fair few have to be taught how to handle the Cross Media Bar for PlayStation systems.
The short of it is that neither Sony nor MS can be an effective threat to Nintendo's sub-market at this point. They lack the controls, the interface, AND the games that it would take.
