As much as I'd like an XB360 solely for Tales of Vesperia the system would be wasted in my room. I just don't like most of the major exclusives (Halo, Gears of War etc). It seems a waste to buy a system for just 1 game.
I'm thinking of buying one when they current console cycle is at the end. Cheaper system, cheaper games and not that many games being released on Wii/PS3.
