Normally, I would say that a Thor movie would not make that much, but with The Hulk (among others) in the movie, it's harder to say.
Also, there is always an unexpected kids movie that makes more than was predicted.
Agreed. There are only two (1.5) planned that I know of, Captain Marvel and Ant-Man and the Wasp. I expect the later to marketed as both characters being lead. Captain Marvel will be directed by a woman, Anna Boden, with her frequent collaborator Ryan Fleck.
I would be shocked if there is not a Wonder Woman 2. And I imagine Patty Jenkins would direct again.
