Couldn't agree more. It's even more scary now that we know the game is feature complete, and so pretty much what we see is what we're going to get... Hopefully various little quibbles and issues with all the WIP footage will be somewhat (mostly) gone and it'll look like everything we're hoping it to be. Damn exciting, but I am nervous as to what we'll see and how everything will look.
I dont actually think we'll get to see more footage, in the literal sense of the word, just hear and read impressions, thats what usually happens.
But even in that realm, yes I feel like that, as more and more the game gets closer to be complete naturally one becomes a bit nervous about knowing you'll have to start accepting what you get, and not just give constructive criticism for things that you want changed.
