I just got my copy of
The Art of Iron Man 3. Really awesome art book similar to all other Marvel Studios art books. It shows you more than what you see in the movie. Design of all suits Stark made since the Mark 7 suit in The Avengers. That's mark 8 all the way the mark 42. Some are seen more visibly in the movie's final battle. One of them looks like Frenzy/Rumble with "pile drivers".
