I'm sure they will do what both Marvel and DC has done dozens of times in the comics. That is make Captain Ersatz of spider man/x-men characters and include them in the movies. Then they do that until they can buy the rights back.  Hell as shown in this link Shazam is literally a Captain Ersatz of the original Shazam. I imagine Marvel will likely do something similar in future movies. That is if Fox and Sony don't work with them. If they don't work with marvel it won't be hard for them to make a Captain Ersatz. The great thing about the fact that both Marvel and DC opened up comics to the multiverse, is not only do they have the possibility for infinite stories and dimensions, but if they want to they can sell off the rights to one dimensions version and make a movie with another.

Take spider-man for example. Sure they can't make a "Spider-man" movie without permission from Sony Pictures, but that doesn't stop them from having a version of him in one of their movies. Take the planet Doom time line for example. Doom goes back in time and mucks with all the heros so no one can stop him. Peter Parker never becomes spider-man but instead dawns a cool black outfit and calls himself "Slinger" Even changes his phrase "my spider sense is tingling" to poke fun/give tribute to the populer DeadPool meme by changing it to "My common sense is tingling". So there is no reason they can't do something like that with all the characters and they have more than enough source material to run with.

The film industry is going to collapse soon. Someone needs to save us from all these superhero movies.

I just ran across this, which is interesting:

"Feige says the “opportunity exists” for the Defenders — a team that includes Daredevil, Luke “Powerman” Cage, and Iron Fist — to graduate from Netflix (where their individual series and Defenders team-up will begin streaming next year) to the bigs."

I hadn't heard about that before.  The Defenders are an interesting group.  I can't help but wonder who the members will be.  Valkyrie would be awesome.  So would the Sub-Mariner.  Moon Knight?  Hellcat?  Hercules?  Gargoyle?  He was cool.

Moondragon would be perfect but I don't know how that would fit in with the Infinity Gauntlet storyline.

A lot of possibilities for the defenders. During the Planet Doom time time Spider-man or "Slinger" was one of the defenders. So there are a lot of possibilities open to them. I am just disappointed tho that the Daredevil "Series" is really just a made fro TV movie that's broken up into many episodes. I'm sure it will be great, but there is no real chance it will be continued after it's conclusion.

There is no way a few of these will not flop.
Besides, I doubt America will still be standing tall at 2018.

Always wanted a Black Panter Movie

Hopefully they don't f** it up

Personally, I think the Marvel movies are getting better and better
