People have been speculating on what [Captain America 3](movie:994409) will be about, and some have been saying Civil War is what the story will be. Now don't get me wrong, Civil War would be awesome but there is so much more that Marvel can do with Caps story. I personally would like to see MODOK and AIM in the film.
Even Arnim Zola could be a possibility as well because of his minor role in the Winter Soldier. It would be nice to see where Hydra is at in the Cinematic Universe after the events of [The Avengers: Age Of Ultron](movie:293035). As suggested by many fans, Cap may die and the shield will be passed on to someone else but that should be used for a later story (maybe Cap dies in the Infinity Gauntlet by Thanos while sacrificing himself for the survival of the human race).
I believe that Cap 3 should set up Civil War because we've already had confrontations with Cap and Stark in The Avengers. We all know that in Age of Ultron that there will be some sort of confrontation about what Stark will do with Ultron and maybe show the alliances that Cap and Tony make with the other members of the Avengers. With the presentation at SDCC with Cap's broken shield, I believe that something will happen with Cap that may have some form of connection with the Time Gem.
Many people have made their own logos for Cap 3 and the one that intrigues me is Captain America: The Fallen Soldier. Now we all know that this is a fake title but it could have some potential in that something will happen to Cap and will result in his position in the Avengers and will rebel against them, leave them, take his fellow member start a new team, fight a few Hydra members, Tony finds them, then we cut to the credits that could say something like Captain America, Tony Stark, and the other Avengers will return in Civil War. This would then not be Avengers 3 and help set up Infinity Gauntlet because Thanos finds Earth in state of weakening because of the fighting of the Avengers.
As I said before, I believe that Captain America will sacrifices his life at the hands of Thanos in order to save Earth. This could have impact on the previously split teams coming back together to honor what Cap stood for, end with the funeral for Steve Rogers, and show Agent Coulson telling Bucky that it may not be what Bucky wants but the world needs a Captain and he is one that can do the job.
Chris Evans has stated that he does have a few films left on his contract but maybe Marvel will persuade him to do a couple more and will allow ending Evan's Captain. Whatever the case maybe for Captain America 3, it will be mind blowing just like the Winter Soldier.
