Id Software technical director John Carmack has said that it's easier to realise the potential of the Xbox 360 hardware but that the PS3 has certain theoretical advantages, and he speculates that Blu-ray could play a decisive role in the console war in future.

"What you can say really quite clearly and not get into too much argument about it is that the 360 is much easier to develop for, it's easier to get the performance out of it that it can deliver, and the rasterizer, the GPU side is generally faster than what the PS3 has," Carmack told Eurogamer at QuakeCon.

"You could design a game where the PS3 would be the superior platform, but you'd have to go out of your way to do it. If you're doing a game like people just want to do games now, the 360's the better platform."
