I have joined just to post this article although I am a very old member of this page so please don' judge me.
I was looking for some Iron Man 3 spoilers and came accross this forum posts that talks about some inside news so have a look...
I am not posting all of them but some are the interesting...
General Ross is either mentioned or has a cameo that is to remind Stark about their deal during Incredible Hulk.
The Armor shown a Hulkbuster is actually a prototype on which he was working on Ross' request but later stopped.
James Rhodes shares a scene with a woman called Captain Denvers.
Dr Pym gets multiple mentions in movie.
Here is the post #335
