This debate is getting rather redundant and pedantic now. Simple: both Digital Foundry & LoT said Killzone 3 not only performed better than Crysis 2, it looks better than any other console game on the market. It didn't get much more to the point than that, especially from Digital Foundry (who I trust more than any review site).
Far as I'm concerned, with Battlefield 3, Uncharted 3, & RAGE not out yet, these debates should hold off until they are released and properly/professionally analyzed. You guys are just going to keep going in needless circles until then anyway.
IGN and many other like it say different and there is nothing you or anyone else can do about
