http://www.efavata.com/CBM/index.htm has this image (posted below) as to what their insiders tell them that the new Ironman costume will look like.
they would have to put platforms in the suit.
The whole point of being Ironman is that Stark doesn't need to be a huge peak human guy. He gets in a big high tech suit and kicks ass. Stark could be kind of shrimpy, as long as he's smooth with the ladies.
That pic is probably just a fake. Probably some old holographic Fleer card of the modular armor.
Yeah, in the comics it was called the modular armor, because it was supposed to be easily modified, adding extra blasters or armor when needed. This was a great idea, but vastly underused, though it did culminate in the Hulkbuster armor.
It was used in his own series for a little bit, in Force Works (great series, basically the sequel to the West Coast Avengers, but they broke off from the Avengers purview) and in his animated series in the 90's.
