Well, having played both the 360 and PC Demo's, I've decided to go with the 360 version tomorrow. The experience was just so much better on the 360 for me. I have a pretty decent computer (C2D @ 3.4ghz, 2gb ram, 8800GTX, Vista w/ DX10 and 24" widescreen display), but the surround sound system and HDTV just won out big this time.
