Well, if you're looking to get a Wii, Gamestop.com will be taking pre-orders on Thursday evening. They didn't state a time, they just said CST. The only thing that sucks is that you need to buy a bundle for $699, which I never have any problems with that because since it's a new system, I'm gonna buy a couple of games and an extra controller anyways

Good luck getting in on one, if that's what you want
