I say you're all idiots for not just going with whatever system you like and leaving it at that.
On a serious note, while I'm also a Nintendo fanboy, and plan on buying a Wii, I think that the Xbox 360 will actually turn out the best. Sony's knocked many fans away, including myself, with how they're planning the PS3 (Killzone 2 rendered in real time my furry ass...), and the price itself turns off many others. Sure, if you have a job and save up, you can get it, but when I can get both a 360 and a Wii, thus capturing the full extent of two different kinds of games (two kinds that the PS3 attempted to combine), for about the same amount of money, I just don't see how it's worth it. Fancy Blu-ray disc/pretty graphics or not.
Save for the extra graphics power (and the motion sensor controller), Xbox 360 pretty much does everything the PS3 does, except at a more modest graphic/sound quality level. This more modest display (which still looks damn awesome) also comes at a more modest price, so it's less of a sting on one's disposable income. And I'm getting the Wii because, like the DS, you're not going to get some games for it to go multiplatform. Yeah, I'm looking at you, Sonic Wild Fire.
EDIT: Wait, doesn't this belong in the VG forum?
