I haven't really been keeping up on NG (although I'll be there day 1 most likely).
To be honest that cutscene doesn't look so much different (holy crap... tits). I was thinking a more contrasty lighting engine like Assassin's Creed. I guess the difference is AC only had one lighting source, being the sun. NG would have a few, which might be hard to pull off.
I hope the cutscenes are all real time as CG to real time can be a bit jarring, especially in NG.
