If I have enough money, I'll buy it. But I'm waiting to buy any next-gen console until all of them are out, and I can really see what I'm buying. No sense (to me) to blow $600.00+ on a 360 and then see the PS3 or Revolution come out with better games/new innovated software.
I know that I'll definetly wind up buying a 360 or PS3, at least for Brothers in Arms: Hell's Highway. The only reason I'm leaning toward the 360 is because of the price. Also, I may wait until they can really figure out what they can do with the Revolution. It may take a year or two for that Killer App to appear, and personally I don't want to see a $200.00 system sitting in my room, collecting dust for that long.
