That video shows all 3 consoles playing COD3. To me it looks close between the PS3 and 360 with the Wii being the worst (Although I've been told Wii is the most enjoyable to play COD3). Probably the 360 looks the best but you couldn't tell a difference between that and PS3 except the PS3 brightness seems to be turned up.

I dont think there is much difference in graphics. If you have a nice big HDTV you wont see any difference whatsoever. It's like saying which one has better sound I think. Probably near the time the next consoles are being released will be when the PS3 starts to dominate but at the moment, the 360 is winning and looks set to dominate for a while because thye have better games. Remember Sony lose money everytime they sell a PS3 and all the good games are going to the 360.
