If they stick close to the Civil War comics then Steve Rogers is killed off by the end.
If Chris Evans did want to leave they could have Bucky Barnes take over the Captain America role.
I think he's done great as cap. It's a bit like Hugh Jackman and Wolverine - it's become "his" role.
I kind of feel the oposite to you Skeeter. At least about Civil War. There aren't enough yet for them to do it. Yes, if they were able to bring in X-Men and Fantastic 4 too, and the Inhumans from Agents of SHIELD, there would be more reason for there to be registration. But at the moment there are only 15 or so superheroes. There aren't enough to be a Civil War, just an argument amongst a few people.
But yeah, I think there should be more solo movies before they can do a Civil War.
Where is the Guardians of the Galaxy 2 ? That i'm looking out for !
Xmen, Batman Superman, there is plenty to watch this year!
Ultimately I hope to see a movie about the dwindling number of humans who aren't superheroes. Their story of determination to survive in the ruins of civilisation, never knowing when suited figures might randomly appear and begin another tranche of destruction...
