Overall, I think this is one of the most graphically impressive games out there. Not just on console, but PC too. In moments it simply looks phenomenal.
This is one game where the slight blurriness of the image, guessing from 900, doesn't bother me much. Might sound stupid, but I do see where they are coming from with that filmic look. You do lose some macro details in going for that look, but it still looks great overall. It is a shame the frame rate consistently runs at sub 30fps though.
But the AA solution seems really good on all but the most distant stuff. Overall it helps to clean up the image, and as a result it still looks far better than say, F5 even though the latter is 1080p.
One thing I will say is that I haven't seen any segments with many full AI characters on screen at the same time, nor particularly open levels. I've heard there being mention of these, but I haven't seen it myself. Everything I've seen from a playable standpoint seems very focused and linear. In-fact, at times even somewhat claustrophobic due to the immensely close up camera.
Even in that opening scene with the big colosseum structure in the background, didn't seem like you could really move any where but forward, and with respect to full AI characters, there weren't as many as I'd have expected on screen at once. The large row of soldiers clashing in the far distance don't seem to move or change action (eg not full AI till a triggered sequence) until you're right up to them either.
