Yeah I think all of the consoles have decent diversification in their library's, it's just that the Wii's caters more to the casuals than the hardcores, while the PS3/360 cater more to hardcores than casuals.
Games like MySims would never do near as good as they did on the Wii. But at the same time, RE4 (a port, yes), has sold nearly the same amount as the RE4 game did on the GameCube. And I know the game is only $30, so that probably has to do with the sales, but trust me, the people buying that game are clearly not your Mario and Sonic fans (or at least not only). People don't just buy games unless the plan on playing them, no matter how cheap it is (except for WiiPlay... because you never know when/if you will play it).Edit: well i guess that's not entirely true... $5 games you might pick up on a whim... but $30 games, probably not.
As for the 360 and PS3, like I said, are not failing in having a diverse library, it's just that they don't have the price point or the games to get the mainstream appeal, which is really needed for a console to succeed. The PS2 (and PS1) would never have done so well if they hadn't catered to the casuals (and Sony also focused on expanding the European market, which helped a lot). There just aren't enough "hardcores" out there to "win" a generation.
I think this generation will be interesting because the casuals (and many non-gamers) will go for the Wii, while a lot of those gamers that play a lot of games, but aren't really hardcore, will go for the Wii plus one of the HD consoles, and then the most hardcore of hardcore will own a HD console, and a Wii (since that's where a lot of franchises will go), and will ultimately lead to higher sales for each console compared to the last generation consoles. Meaning the Wii will sell more than PS2, and probably A LOT more, and 360 and PS3 will sell more than the GameCube and Xbox (though that's not hard to tell, since they're only a combined 13 million away or so). The Wii will be the clear "winner," but overall, the consumer will be the true winner.
