I watched it. It does contain spoilers, but hell it's only the first 30 mins. I figured on Jan 29 ( EU ) I will quickly past that bit.
What I will say is I have never seen graphics like this. In fact I have never seen a game experience SO movie like. That term has been thrown around to much concerning some games. This is like the Avatar of Games. It really does cinematic in a way games just haven't achieved yet. The first 10 mins are better than the whole of Mass Effect 1.
It's hard to believe there is no CGI. I know it's running on the latest Unreal Engine 3 mods ( Global illumination etc ) But damn. At 6: 13 in the first part, just WOW. I mean WOW.
