Kevin Feige reveals the titles for the rest of the Marvel Studios films in Phase 4 will be announced after Avengers 4 comes out.
In an interview with io9 while promoting Spider-Man: Homecoming, Marvel Studios president Kevin Feige shared there won’t be any announcements about post-Avengers 4 films until after the last Avengers film is out.
I think there will be certain elements that start to come about, not the least of which is the already announced release date of the next Spider-Man film.
After two successful Phases in which the audience has come to know heroes such as Ant-Man, Thor, and the Guardians of the Galaxy, the MCU as we know it will come to a conclusion with the still untitled fourth Avengers film, which also marks the end of Phase 3.
