You already fucking know what the game looks like. There have been quite a few demonstrations of the game so far. After you've seen most aspects of the game in action, what's the point of seeing it continuously until release? That's something I don't think I'll ever understand. I really don't need more than three or so demonstrations to get a good idea of what all the game is about. I'd rather be visually thrilled for a few minutes at that point.
I freaking love well done CG trailers and I hope they never go away. Of course, this isn't the full trailer, which sucks.
