I heard about an extended trailer, but I thought it was going to be one day later rather than during the main E3 presentations.
Kiefer Sutherland's done pretty well by Big Boss, I think. He's still got some of the growly inflections when he's talking, but like Kojima mentioned in the pre-E3 video, it's still a much more subdued performance that he's going for.
Still unsure of what David Hayter's doing. Either he's in terrible, heart-breaking denial or he's in cahoots with Kojima for a major trollmove.
