For Iron Man I always saw them setting up to use the Mandarin, in Iron Man they show the leader of the 10 rings being disabled, but not killed. I like the way they kept the Hulk relevant in The Earth's Mightiest Heroes cartoon, but in that universe the Hulk can talk and can also be calmly watching TV without reverting to Banner. I wouldn't be surprised if they brought the Red Skull back in later movies simply because they've already cast him with a recognizable face.
