Same here. I'm hoping that trailer 3 is the longest, and sheds a bit more light on the characters. I know a lot of people would call it cheesy, but I think it'd be cool to have some portrait shots in the next trailer highlighting each character and displaying their names. Basically, I want the next trailer to be our "character" trailer, which gives us an idea of who each of these guys is and why we should think they are bad ass.
Maybe the first half of the the portraits would start with a card reading "HEROES" and highlight the Joes, and the second half would have a card reading "THE ENEMY" and highlight the Cobras to-be Destro, Storm Shadow, Zartan, Baroness, and The Doctor. End with an action montage and a one liner, and I think that would be enough to get the audience sufficiently pumped.
