Avengers 4 - After the Infinity War Theory

I am interested to hear what everyone thinks will happen after Infinity War. Will everyone come back from the snappening or are they really all dead? Will Captain Marvel lead the new Avengers or is Iron Man going to create his own gauntlet from vibranium?

 

I was left hanging. All those folks that got snapped need to come back.

 

I read the comic books and apparently, in the original story, Gamora is trapped in the soul stone with Adam Warlock and all the other people that Thanos killed with the soul stone. They are able to escape, but the directors said that all of them are really dead. The time stone can bring them back though. I don't know how that will work out.

 

Maybe time travel,
In antman and the wasp, a time vortex was mentioned.
