Commentary
New Mutants date was shifted?  It was long rumored that New Mutant would be shifted to a direct to Video release, possible a Hulu Movie.  But shifting it to a position that isn't necessarily a dead weekend in the box office, and directly against an announced DC Film, but not a prime Marvel Film weekend is interesting.    The film is scheduled to get further reshoots later this year.   Is Kevin Fiege involved?   Something is up here.


The oft delayed Gambit, which was supposed to go into production this summer, but currently does not have a director attached has been indefinitely delayed, Not Canceled.   Normally indefinitely delayed does mean canceled, but Disney has officially canceled a few 20th Century movies in development.  So why is this one indefinitely delayed instead?   Gambit, like Deadpool is film that should be in the R-Rated space, as the character is a gambler womanizer and adult oriented humor.   Could it be that Disney wants to revisit after deciding what to do with Deadpool and Blade?

Three films that are not canceled from the Fox list, Deadpool 3 (X-Force), the Logan (Wolverine) Spin-Off starring Daphne Keen as Laura/X-23, and the Mystique standalone film.
The Deadpool film is easy to understand but the other two are interesting in the fact that they were announced during the acquisition and their status was not addressed in the press release. 

Where are the problems.
The sequel to Captain Marvel has not been announced is not on the list, but it has to go somewhere.  What about Ant-Man and the Wasp sequel?

Currently Marvel Studios has three movies in preproduction that are prepared to go to filming.   The Black Widow standalone movie, The Eternals and Shang-Chi.
The other announced films are currently also in preproduction but do to scheduling and other requirements not ready to go to filming stage. 

• Black Panther sequel - Not on anyones schedule until mid-late 2020 for filming.
• Doctor Strange sequel - Benedict Cumberbatch schedule is full until 2021.
• Guardians of the Galaxy Vol 3, is slated to be filmed after James Gunn finishes filming Suicide Squad for DC Studios.  
• Ms. Marvel - No one is attached to any major points.

If we start slotting Films in the release schedule:
2019
June 7 - X-Men: Dark Phoenix
July 5 - Spider-Man: Far From Home
2020
April 3 - X-Men: New Mutants
May 1 - Black Widow Standalone
October 2 - The Eternals
November 6 - Shang-Chi
2021
February 12 - Deadpool 3 (X-Force)
May 7 - Captain Marvel II
November 5 - Ms Marvel
2022
February 18 - Ant-Man and the Wasp sequel
May 6 - Black Panther sequel
July  29 - Guardians of the Galaxy Volume III

This leaves both the X-Men sequels (Mystique and X-23) off the list as well as one MCU announced film, in my case I left Doctor Strange sequel but it could be Ant-Man and the Wasp.  The reason I left Doctor Strange off the list is because with film not planned until begin filming until mid 2021 can it be ready by 2022? 
If the two X-Men films are being left off the list why were they not indefinitely delayed or canceled?


The question is what happens in 2023?
Why are no films announced for 2023? 
April 28th would be the logical release date for the next Avengers film.     February 10th the weekend before the Presidents Day weekend has a live action Disney movie listed for a release date.   That creates a challenge to build hype in the way the Black Panther and Captain Marvel lead into the last two Avengers film.   Do you drop a film there?

This leads me to believe that one of the following things is true:

• One of the movies that Marvel has announced (or not Announced but we all know is coming) is further along in development than we know so it can be slotted in the February 12th 2021 release date.   
• There is another unannounced movie in the works (Avengers).
• The next Avengers Film is released in 2024
• There is an X-Men film planned for 2023.

Edit:
I should note the above list does not include a Spider-Man sequel (third) movie.   As of today neither Sony nor Disney have announced any movement on the Spider-man film rights. 
There is a slot on for a movie release on July 1st, 2021 for Spider-Man in the calendar.
