Marvel Studios President Kevin Feige says that the studio will not announce any additions to its upcoming film schedule until after Avengers: Endgame, the presumed finale of Marvel's current Avengers saga, which may bring sweeping changes to the MCU.
Speaking at a Captain Marvel press event (via ComicBook), Feige explained that, while Marvel has planned films, the studio won't reveal the details of what they are until after Endgame and its immediate MCU follow-up, Spider-Man: Far From Home have been released.
"As we've been doing for years, we aren't going to announce anything post Avengers: Endgame or [Spider-Man: Far From Home] until post Endgame and Spider-Man," Feige explained. "As you know as a fan, there's a tremendous amount of potential and a tremendous amount of additional characters and storylines and groups of characters that we're going to keep playing with. And again, that's a testament to Marvel and to the amount of storylines and characters and amazing, amazing runs that have been in the Marvel comics."
The lack of information about their May (or late April) 2020 release is not insignificant. While Feige is correct Marvel hasn't announced any new films for years, this will be the first time fans don't know what will be becoming next this late in the release cycle.
Marvel Studios films tend to begin principle production about a year before release, with news of signing directors and casting coming months before. Marvel seems to be working with the cooperation of the larger Hollywood trades, who dominate first reporting such news, to keep whatever will begin production sometime in the next couple of months completely under wraps.
That's not to say we know nothing of what's coming up. Marvel has confirmed that Black Panther 2, Black Widow, and Guardians of the Galaxy Vol. 3 are all in the works, while plans to introduce the Eternals are also developing. It's also been reported that Doctor Strange 2 and a Shang-Chi film are in Marvel's plans.
In October 2014, Marvel Studios announced a four-year slate of nine films scheduled to run all the way up to Avengers: Endgame (which was called Infinity War Part 2 in its initial announcement). Considering that slate ran all the way up to, well, right about now, it may be just about time to expect a new wave of announcements - maybe at this summer's Comic-Con International: San Diego, or Disney's D23 conference?
Avengers: Endgame is due out in theaters April 26.
