I got into the beta for Killzone 3 and I honestly really couldn't tell any difference in graphics between Killzone 3 and Killzone 2. Game still looks just as detailed like Killzone 2 did, but I'm not sure its a noticeable enough improvement from a graphics standpoint. Maybe in the full retail game it will be...
If Uncharted 3 matches Uncharted 2 I think I would award that best graphics over Killzone 3 at this point because I thought the graphics were better in Uncharted 2 over Killzone 2. Seeing more colors in Uncharted 2 might have some influence on my viewpoint.
Infamous 2 looks like another serious graphics contender btw. Seems like a huge improvement over Infamous 1.
Crysis 2 and RAGE are no slouch either. They look amazing. As for Brink I'm not as blown away from a graphics standpoint based on the HD trailers I've watched.
Right now based on HD trailers I would rank it: Uncharted 3, Infamous 2, Killzone 3, Crysis 2, RAGE, Brink.
I think I can't help, but be influenced by the art style too. Technically other games may have more going on behind the scenes.
