Despite what we have all assumed, Marvel Studios’ President Kevin Feige has confirmed that Avengers: Endgame is not the end of Phase 3. Whilst doing promotion for Endgame, Feige confirmed to a journalist during an event in Shanghai that Spider-Man: Far From Home is “the end of the 3rd phase.” Have a look at the below video in which Feige reveals the news.
It was widely believed that Endgame would signal the end of phase 3, given that it would be wrapping up the entire Infinity Saga. With Far From Home now set to be the final film of Phase 3 and no further MCU film dates officially announced, we currently do not know which film will kick off the next phase. However it has been previously confirmed that Far From Home will take place after the events of Endgame.
