I'd hate to launch into another huge rant on the Wii. Frankly, it appeals to me about as much as putting a mario sticker on my tv and handing me a remote control.
Secondly, i wouldn't get up at arms about the awesomeness of the Wii and how it's going to be so ridiculously popular. It's new, it's intriguing. if you're at a place where you could A) go look at the even SHINIER graphics on the exact same console and controller you've been playing for, oh, 12 years or B) go try out this freaking wierd new thing that you really have no concept of, of course you're going to try the new jank instead of old hat.
that doesn't mean you're going to drop $300 bucks when it comes in the store. it's one thing to wait a few hours to test it out for free. it's quite another to forego something like the PS3 or 360 which has companies loaded with good developers and game, and excellent familiar hardware, in favor of trying this risky new thing.
And frankly? even my hardened forearms balk at hack and slashing for hours with that damned remote. forget wii.
