Hadn't seen 2 or 3 of those yet, thanks Nsanity!
From what I'm seeing this game is gonna be a real looker, definitely technically more capable than Reach.
Locales they're doing in this game are definitely interesting as well, I love the fact that the sky is really a sky from pillars and clouds, awesome concept.
As for the animation, looking at Cortana's facial expression, it's definitely been improved.
