I gotta say that they have at the moment, but I think plenty of hardcore fans are going to enjoy SSBB, Metroid Prime, and Super Mario Galaxy. They're just getting started, and they've got a big job to do with appeasing both new players and old fans. It's a tough balance, and they're the only ones doing it. I'm not afraid. The DS is pretty dang hardcore, and it appeals to the other crowd too.
It's awfully tempting, expecially when it comes up on GameSpot's website. But once you look at what you need to do - credit card deals, solicitation offers, etc., it's kinda not worth it. Better to save up and buy one, I say. If anybody has some connections for getting a good 360 cheap, PM me.
