Realize that several people who grew up with a NES, SNES, and/or N64 already have children, and therefore a lot less time to devote to such things...
It's not like they don't have other consoles which they aren't avidly using.
And as with most new consoles, the biggest games were not released on the same day. Zelda is slated for 2013, I guess (lol, Zelda always gets delayed), but it's going to take a year or two before the games that people, especially Nintendo fanboys, really want are released.
But, in the case of the people I am speaking of, they were excited for the Wii even beyond Twilight Princess.
...and some of us are actually in between children and grand-children right now, but have other hobbies and are having a mid-life career crisis (and therefore have little time for gaming for other reasons).
Sure, but if it was something that blatant I would have mentioned it. Again, the people I'm thinking of are still regularly to be found at game-stores on certain Tuesdays. They're just not doing that sort of thing for Nintendo stuff anymore.
