The dude who becomes the villain the Leader is in the movie too which is gonna be great for the sequel, and Iron Man (Robert Downey Jr) is supposed to cameo in a special scene after the credits to help set up the Avengers

They've got so many references in this one it's just sucks it wasn't hyped up like Iron Man was. I agree the Hulkbusters were sweet
