As part of the Q&A, Michael Bay repeated his Obama story clarifying that Obama's "role" in the movie is he is mentioned as the current President of the United States. They also discussed Shia's continuing to work with the hand injury (and special hand cast that was built), Ramon Rodriguez separating a shoulder while filming (that Bay didn't know about), and that the IMAX cut adds about a minute of extra footage. The videos are from The DishRag (via MB.com). The conference seemed very relaxed but so far have not found video of the whole thing. Five videos below in the playlist.
ComingSoon has what is essentially a transcript of the press conference here.
