Alright, having now watched the entire thing, my thoughts are as follows:

They have done a truly spectacular job. The game seems to flow well, the UI looks intuitive and fun to use, and the environments are breathtaking. The only thing that I am at all sad about is that the fidelity of the character animations seems to have gone down a bit. When he run sideways and walks backward, the animations aren't as fluid as they are now.

That aside, I am just totally blown away, I had moderately high expectations, but this really does look totally spectacular. No telling for sure yet until we can get our hands on it, but, great job so far guys. A big thumbs up to the dev team.
