Charles Murphy's tweet being shared online could be anything and everything. It goes right into the detail presumed official dates along with upcoming Marvel movie titles that could be made official in 2022. We must also consider that the one defined as Phase 4 of Marvel already announced a few weeks ago, could easily be the first part, precisely because films like Black Panther 2 o Guardians of the Galaxy Vol. 3, widely formalized, have not yet had an official date.
Precisely these two are mentioned with a lot of alleged dates, with Black Panther 2 out February 18, 2022 e Guardians of the Galaxy Vol. 3 to be released May 6, 2022 - this highly unlikely given that James Gunn is still currently working on The Suicide Squad.
To these are added two other dates, July 29, 2022 and May 3 or 10, 2024 which should represent exit windows of projects still shrouded in mystery. It is not to be excluded instead that, with the Phase 4 complete in the announcements already made, these films can go to build what will be the future Phase 5 of Marvel.
