The trailer as is up on GT isn't IMO good enough to determine much on the tech front, because it jumps around too much. ie. We can't determine the contribution of any realtime indirect-lighting engine.
It looks good, and captures the sense of the E305 trailer. It still looks like a game though. Smoke and fire are still weaknesses, missing the voluminous quality from E305. Lighting seems hit and miss to me too. Some moment look great, but other look plain wrong, such as the descent in the lander. The marines faces are too bright. Shadows also seem to take days off... Post-processing effects looked excellent, giving a very realistic sense of motion, and frantic motion at that.
I look forward to seeing gameplay footage for the sake of getting to take a closer look.
