I just saw a video of his Daily Show segment

He complained some about how the studios were against him, marketing problems, etc. Almost sounds like he is already getting defensive in case the movie isn't a success.
The short video clip at the beginning seemed slightly less "video gamey" than the trailer sequences at least, but overall I'm still not optimistic. And I'm currently getting my WWII fix playing Company of Heroes, so unless somehow this gets great review I'll probably wait for it to come to video.
There is one unfavorable review on rottentomatoes from somebody who says he went to an advance screening, for what it's worth.
