I think it will be possible for Ironman Suits to be real, but I think scientist will be more interested in making robots which can control flying suits with their computer brain rather then a guy in a suit controlling it since Computers in the future might think faster then any human in the world, and it seems kind of dangerous having a man in a suit which is robotic since the suit might explode if something goes wrong.
I think the helmet was the only real moving component in some scenes? I "think" I saw it somewhere but I could be wrong. But I wouldn't like it to be real lol, one wrong person gets it and we are doomed.
I think that the ironman suit will be real someday, but only for military purposes. A suit like this could save a lot of lives and maybe end the war in Afghanistan.
It would be both, the most awesomest thing in the world and the biggest threat to human :-/
Imagine if the suite someway gets into the wrong hands of the terrorist, that wouldn't be a good news :-/
Just wanted to comment in lol, for some reason I don't remember some of the things in that trailer even though I watched the movie. (I thought it was Iron Man 3 )
