Besides JUSTICE LEAGUE and AQUAMAN, there doesn’t seem to be many official releases for the rest of the DCEU films. Sure many have been announced (GOTHAM CITY SIRENS, BATGIRL, THE FLASH, SHAZAM!, GREEN LANTERNS, SUICIDE SQUAD 2, THE BATMAN, theoretically still CYBORG). However, according to Scott Mendelson of Forbes, it seems Warner Bros. has finally scheduled at least two untitled DCEU films for 2020:
Speculation for at least one of them is WONDER WOMAN 2, and the other could conceivably be anything. Maybe we'll hear it during Hall H later this week? Hell, for all we know it could be PLASTIC MAN or a BOOSTER GOLD movie at this point!
Meanwhile, you can see the current roster of DC heroes next in JUSTICE LEAGUE November 17th.
