Among the many DC Extended Universe films that are currently in some stage of development without an official release date is The Flash solo movie, as well as the Suicide Squad spinoff Gotham City Sirens and a direct followup to Zack Snyder's Superman movie reboot, Man of Steel. That's just the tip of the iceberg too, as the list of DCEU movies that are actively moving forward without a firm launch date in place (yet) includes director Matt Reeves' The Batman, the Dwayne Johnson-headlined Black Adam movie, a Birds of Prey film and a Nightwing solo movie from The LEGO Batman Movie's director, Chris McKay.
Over the past year, there's been much in the way of reported activity on a number of those same DCEU movies. The Flash, for example, was seemingly all ready to begin filming at the beginning of this year, before writer/director Rick Famuyiwa stepped down in late 2016. Meanwhile, Gotham City Sirens (by most accounts) continues to make steady progress forward, with not only a director (Suicide Squad helmsman David Ayer) but also a screenwriter (Tomb Raider reboot writer Geneva Robertson-Dworet) and one of its three central stars (Margot Robbie as Harley Quinn) in place already. As for Henry Cavill's Superman: a Man of Steel 2 script is in active development and has been since last fall, but there hasn't been a major update on the project since.
We may now have some fresh details concerning the release date windows for the three aforementioned DCEU films, thanks to "leaked" information that was posted on a DCEU sub-Reddit (via Screen Geek). According to the post, Gotham City Sirens is targeting a February 2019 theatrical release date, putting it a few months ahead of the current release date for the Shazam movie. Man of Steel 2, meanwhile, is supposedly taking the November 2019 release date previously reserved for Justice League 2, while The Flash is apparently being put on the back-burner for a 2020 release (the same year that Cyborg and Green Lantern Corps movies are scheduled for).
While this information should (obviously) be taken with a healthy helping of salt - given that it comes from Reddit - there is fair reason to believe that it's accurate. For starters, this comes from the same source that claimed Joe Manganiello is playing Deathstroke in the DCEU, long before the news was made official. Moreover, these release date windows more or less align with other recent progress updates concerning these three DCEU installments.
It's to be expected that Gotham City Sirens would be fast-tracked ahead of the Suicide Squad sequel's release, given the popularity of Robbie's turn as Harley Quinn from Ayer's (yes, Oscar-winning) first Suicide Squad movie. The early 2019 date would give the film sufficient time to make its way down the pipeline, thus avoiding the blowback that Warner Bros. and DC endured for Suicide Squad's rushed development process. Alternatively, with The Flash struggling to hold onto a director and now undergoing rewrites, the movie (once scheduled to arrive in March of 2018) is unlikely to hit theaters until 2019, at the earliest.
As for Man of Steel 2: with many DCEU fans wanting to see a truly Superman-focused followup to Man of Steel (e.g. not the shared universe launchpad that was Batman V Superman: Dawn of Justice), WB and DC have good reason to prioritize getting such a project off the ground at last. Snyder is following up Justice League with his passion project The Last Photograph rather than Justice League 2 and Man of Steel 2 reads as being a sensible replacement for the latter. That said: with so many films currently in the pipeline, the larger game plan for the DCEU may be equally fluid right now.
