And I AM glad that when they made this movie they didn't just have Tony use another "copy" of the last movie's suit. And the Mark IV is still similar enough to the original suit aside from subtle differences in the shoulder pads, gauntlets and chest to not look completely alien. But it also suits Tony's personality from the comics. I mean the Mark 3 was basically a suit he used for really two battles. The one in Gulmira and with Monger. After that, part of the suit's purpose was for showing off and doing some odd hero work here and there. Mostly I think its Tony's new favorite toy. He probably wears the armor to pick up his own damn dry cleaning LOL since after all, Pepper is the new Stark CEO.
I'm still curious to see how the whole "Natalie/Natalia/Natasha" thing works out in the film. I don't really want to read the novel because I know it won't feel like the movie and y'know I want to be surprised! But I'm wondering if she'll be playing the good girl for the most part or if she'll be like her Ultimates incarnation and sort of a double agent, who screwed Tony so she could get access to his armor tech. I still think the latter will be in the film, she'll flirt and be well... ScarJo... woman can get a rise out of a frakkin' statue!, but I think she's working more for SHIELD than the KGB.
Seems like there's a lot of movie in this movie. Whiplash, Hammer and his armored drones, Black Widow, the Stark Expo, intro of War Machine. Gonna be a big ass movie.
