I'm looking forward to it as well.
I've always liked their behind the scenes videos, and I'm sure I won't be disappointed with the ones they'll do for Uncharted 3.
I know Drake's Deception will be technically more impressive than Among Thieves, but I think people shouldn't expect a jump similar to the one between Drake's Fortune and Among Thieves. There's only so much you can do to perfect what is already flawless (this is a figure of speech, ok? :P).
