Also it seems like they showed off the PC version over there, since he said: "From the look of the 360 footage visually it was a bit of a disappointment. The graphics were by no means poor, miles ahead of many games this year and worlds apart from Oblivion and Fallout, however compared to the amazing scenes we have seen on the PC footage it just came as a disappointment."

Also its funny that the crowd booed when they said it was shown on a 360, just like at quakecon.
