Avengers 4 was previously known as Avengers: Infinity War Part II, but, in 2016, that title was removed to make it clear that this was one singular movie as opposed to the second half of a larger story (the real title has yet to be announced).
Unlike the previous three year gaps between Avengers movies, Avengers 4 will be released only a year after Avengers: Infinity War, on May 3, 2019.
What Is The Avengers 4 Release Date?
However, Marvel fans should still expect close connectivity between Avengers 4 and Infinity War, hence why they don’t have to wait nearly as long for the follow-up.
