"Now that Phase 2 of the Marvel Cinematic Universe has officially reached its conclusion with the release of Marvel’s “Ant-Man,” we have new details on what to expect in Phase 3!Which isn't necessarily anything to be proud of after a decade and all of these films and she's sharing the title but it's a start. Nevertheless MARVEL clearly think they have something here because in order to incorporate the film, they're shifting the Phase 3 schedule around again:
"Following our hero’s debut adventure in this summer’s “Ant-Man,” Scott Lang will return alongside Hope Van Dyne on July 6, 2018 with Marvel’s “Ant-Man and the Wasp.” The sequel will mark the first Marvel Studios film named after its heroine."
"Additionally, Ant-Man’s second adventure will lead to a couple of other films shifting their dates, with Marvel’s “Black Panther” moving up to February 16, 2018 and Marvel’s “Captain Marvel” landing on March 8, 2019.Which also confirms the existence of a Phase Four after The Infinity Gauntlet in the year when I turn forty-six. This means that Phase Four will end when I'm fifty years old. Jesus.
Finally, three untitled Marvel Studios films will premiere on May 1, 2020, July 10, 2020, and November 6, 2020.
No word on director or writer yet but I'd be quite pleased to see Peyton Reed return should he want to. The storyline seems pretty obvious -- the two of them entering the microscopic realm to find Hope's mother which sounds like it could be quite expensive. Also it'll be about who's cast as the mother. Perhaps we'll finally get Meryl Streep into the 'verse.
Here's the new revised release schedule.
