Avengers ship Hulk off to a different planet because they fear he can't be controlled. It is a horrible storyline. I hope Marvel doesn't do this. He is much better served as a protagonist with serious anger and control issues like they have been portraying him.
Also, talk of Civil War for Avengers 3! That would be amazing! It would be great if Marvel could buy back the movie rights to Spiderman, The Fantastic 4 and the X-Men before the movie, but that would be extremely expensive to buy those rights.
