Hm, I really like the idea of Planet Hulk leading into a World War Hulk inspired Avengers film. I can't say I'm really all that thrilled about Ant Man (and Wasp) being seriously pursued though. I'd much rather see Doctor Strange, Vision, or the Scarlet Witch. There are others characters that I'd personally love to see, but I think their stories would be difficult to work around, like: Namor, Black Panther, and Luke Cage.
