I'm intrigued as to what they'll come out with, but I have no hopes for Nintendo's home consoles anymore. It's been the same formula for too long: the multiplatformers, which tend to include the only games that interest me, are by far the worst on the Nintendo console, and the only games that are guaranteed to be at least worth playing are Nintendo's franchise titles, which personally don't interest me anymore even though I know they're good quality. The N64 started this trend, although to a lesser extent than the GC and especially the Wii. It also helped the N64 that its third party games, in contrast to the Wii, were often NOT absolute drivel.
Back when the Wii hadn't been out very long, some developers said they'd shift their focus on the Wii, which I felt was believable and understandable due to the system's mass appeal. We all know how that turned out, however.
I'm slightly inclined to give Nintendo the benefit of the doubt, though, because there's a possible, but unlikely outcome here. If the next year's console will have decent hardware compared to the inevitable next Xbox and Playstation, and Nintendo puts great effort into modifying its image as a mere casual gaming system, it may also become a worthy console for games that AREN'T Mario or Zelda or some fitness game (though even those are better on the other consoles right now...) Unfortunately I don't see this happening, because with their current strategy, business has never been better.
Looks like we're not going down after all, so nevermind.
