Will it be possible to do better than KZ2 in terms of graphics on PS3?

The footage of Heavy Rain last E3 alone looked better than Killzone 2 IMO. I'm sure that KZ2 is much more technologically advanced because of all the things it has to do at once, but Heavy Rain's character models simply look amazing, even up close despite being a 3'rd person game.
