yeah definately sandman, that was confirmed a long time ago by slip of the tounge thanks to dunst in an interview. I don't remember venom being mentioned although I always hoped that if another spiderman was to be made, venom would be a part of it. He would look awesome with the visual effects of this day and age. I expect Sandman was very hard to create too due to the amount of particles needed to create him.
I do hate these trailers that comes out a year before the movie is out though, they get you hyped up knowing you have ages to wait.
Ghost Rider done the same thing to me, I can't wait to see that now after seeing the trailer, yet it comes out next year...I hate waiting. If you havn't seen the Ghost Rider trailer yet, here it is:
