In fact, a lot of the new trailer rehashes what we saw back then. Pepper Potts (Gwyneth Paltrow) is still important to Stark, as he says "Things are different now. I have to protect the one thing I can't live without: That's you," he says, pointing at Potts.
This movie's villain of choice is The Mandarin (Ben Kingsley). As in the earlier trailer, we see the Mandarin’s helicopters launch missiles at Stark’s seaside home, which crumbles and explodes. We also see scenes of Iron Man saving people falling from an airplane, Tony Stark lying in a hospital room, surrounded by doctors, and Pepper Potts held in some type of metal restraints.
We also see Gwyneth Paltrow apparently in bra and -- not sure what else.
Near the end of the 2:45 trailer, we hear the Mandarin say to Stark, "I'm gonna offer a choice. Do you want an empty life, or a meaningful death?"
We also get to see Stark say "There's my boys," as a bunch of Iron Man suits -- presumably robotic -- come to save the day (both Stark and Rhodes are suit-less).
If this trailer is anything like the full film, this could be the best Iron Man film, ever.
