The gamer community (by this I mean people who know and buy many games, not just the few names they've heard about) has always been a small part of the public. Almost every people I know who has a gaming console don't know anything about videogames, and only buy a game from time to time, generally the "game of the moment" that is advertised everywhere. And this includes Wii owners of course, but also 360 and PS3 owners. I see evidence of that everyday.
At work, I have a few colleagues who game, and they all have a PS3. Well, they love it but they still spend all their time on WoW... And when they actually buy and play PS3 games, it's CoD, Uncharted 2, Assassin's Creed, and I'm pretty sure their next game will be GT5. Last time we talked about videogames, they where mocking the Wii ("graphics suck", "the games are stupid", "the GPU can't display blood"). I told them about Muramasa, Madworld, HotD Overkill, they didn't know any of these games. I mentioned RE4 Wii, they didn't even know about this one... Actually all they knew was Wii Sports, Raving Rabbids, Wii Fit and Mario Kart.
Of course all of this is anecdotic, but though there are differences, most of the PS3 owners I know are like this. And it's the same with 360 owners. People happen to know and buy only a few games. Then if you want more evidence of this, look at the attach rates for any console ever released. I don't think anyone can call him a gamer he buys 10 new games in the whole lifespan of a console. That's about 2 games a year.
