Kevin Feige says they have their movies planned through 2021
This is what I'm hoping for.
Avengers: Age of Ultron
Thor: Nine Realms
Captain America: The Last Avenger
Avengers: Civil War
Daredevil: The Man Without Fear
Doctor Strange: The Oath
Heroes for Hire
(The Black Widow and Falcon hire a team of the world's finest non-Avengers:
Iron Fist, Punisher, Moon Knight, Ghost Rider, Luke Cage, Silver Sable, Blade)
Guardians of the Galaxy: The Korvac Chronicle
The Infinity Gauntlet (Bringing all the heroes and villains together to face Thanos)
One could dream.
