Shows and movies that I could find that might come out before THE FLASH (tentative):
DC LEAGUE OF SUPER PETS [animated]--July 29, 2022
THE SANDMAN season 1--August 5, 2022
BLACK ADAM--October 21, 2022
SHAZAM! FURY OF THE GODS--December 16, 2022
BATGIRL--December ? 2022
HARLEY QUINN [animated] season 3--2022?
TITANS season 4--2022?
STARGIRL season 3--2022?
DOOM PATROL season 4--2022?
JUSTICE U season 1--2023?
AQUAMAN--March 17, 2023
They could push THE FLASH further off its current release date. In any event, by the time it does come out, lots of other stuff will have hit the big and small screen. And potentially, for good or ill, things will have been settled with Ezra Miller. So I think they should take a wait and see approach and in the meantime concentrate on these other projects, which could take some of the heat off of THE FLASH.
