Wow.... people are so optimistic!
5 - 6 months isn't a long time to be working on graphics and upgrading graphics, that's part of engine development, so the core 'look' of the game will not change, the only thing that will change are a few extra effects that are added in in the end and little details here and there.
I know this post will sound like a bashing post, but seriously you can see heaps from this screen shot that tell me it's going to be a big disappointment.
The character art is good, and the model detail looks fantastic.
The shadow? What the? The PS3 can do better than that? block polygonal mess, not self shadowed.
The textures in the background and the wall are shocking, they remind me of Super Mario Sunshine disgusting rock wall texture, and the viewpoint gun just looks low detailed and not overly impressive on the texture side of things... quite disappointed am I.
That said, it's only one screenshot and it's a bit un-fair to judge on that, but I think this game deserves all of the scrutiny it deserves since Sony touted that CG trailer as 'in game'.
