no there will be no difference.
people saying that "thanks to worse graphic card ps3 games looks better" - LOL.
uncharted - almost claustrophobic levels = better textures(still assasins creed looks better compared to uncharted if you look at what it got to offer).
FFXIII will take 3-4dvds and will still have same content with the same quality.
i would be more worried about ps3 version being inferior to 360 since not only SE will have more time to work on 360 game(they will be able to fix glitches that may end up in ps3 version during porting since they have already finished game) but also SE already worked on few 360 games so they have enough experience wit MS console(especially considering the fact that last SE ps3 game was canned after releasing 360 version due to technical problems).
