If I hear Gears of War 2 or Resistance as games Wii owners should be jealous of I may have to smack someone.
I don't really understand what it is you're trying to say here. Why wouldn't Wii owners want Resistance and Gears on their console? They're high budget hardcore action games, something that the system doesn't exactly have in spades. The same thing goes for titles like Super Mario Galaxy and Boom Blox. People who don't own Wiis should want those on their system of choice. Variety never hurt anybody.
As for Animal Crossing, it's never really been my bag, but the people who like it will probably like this new one. I will say this, though. A buddy of mine was at the show, and I think he hit the nail on the head with: "Well, it's good to see that they're still getting their money's worth with 64DD tech."
Nintendo's conference this year was exactly what I expected it to be: they're fully embracing the market that's making them tons and tons of cash, and there's not a single thing wrong with that. As a gamer with particular tastes, I don't think I'd be satisfied only owning the Wii, however. The kind of games that I like playing are simply more often than not developed elsewhere.
So while I love playing Boom Blox and Smash Bros. and Super Mario Galaxy, I can only play them for so long. Comparing the Wii and 360's release schedule for the next year, I'm probably planning on purchasing four 360 games for every Wii game. That's not the case for everybody (clearly, looking at sales), but Nintendo's new direction, while fiscally very sound, isn't one that I'm willing to follow exclusively, and I think a lot of people feel the same way.
