If I were to buy another console, I'd choose a 360. I'm not interested in Live, but it's the volume of games I'm interested in, along with the Arcade games, that are the reason I'd buy it. However, as it stands, I don't spend enough time playing my Wii games, in the sense of console ownership, so I've yet to need another console bad enough to pay $200 or more for it. Maybe when it gets around $150 or gets a smaller redesign, I'll reconsider.
My roommate badly wants to me to go ahead and get a 360, and I don't care. For some reason he wants one sooner for Final Fantasy XIII than when the game comes out, and he doesn't have enough money to get one. He hasn't influenced my decisions, because I really don't care about FF XIII, and since I'm the one buying, I'm waiting untill I want to buy it.
