With plans to continue so-called Snyderverse. Sarnoff did recognize the excitement and hard work that the Snyder Cut fans had put in to get this film released, though.
But despite being ive of Snyder getting to release his Justice League movie, Sarnoff confirmed the 4-hour cut "completes the trilogy" since Warner Bros. is looking to go in other directions with the DC brand. Sarnoff's comments about the end of Zack Snyder's Justice League universe have received mixed responses - understandably so. With not much data released on how the Snyder Cut has performed, Warner Bros. is choosing to go forward with other projects and filmmakers. But in the long run, what does this mean for their current DC plans, and what are the chances of seeing any type of Justice League 2? Given that the Snyder Cut is taking place in its own continuity, Warner Bros. has technically been able to release themselves from that world.
But that doesn't necessarily solve the problem that will be on their hands in the near future. While the theatrical cut is what it is, Warner Bros. has still been moving forward with some of the characters in their own franchises. A third Wonder Woman film is in development and Zack Snyder's Justice League 2 and Zack Snyder's Justice League 3 that gets to conclude the director's planned storylines for his trilogy and the main characters, but those characters aren't going anywhere.
The cancellation of the Snyderverse, more than anything, affects Henry Cavill's Superman and Ray Fisher's Cyborg, especially the latter due to the ongoing dispute between him and WarnerMedia. Given that a DC directors aren't considering the Whedon cut as canon to their respective franchises. The only way a Justice League 2 happens is if they create a new franchise after The Flash, with that film doing an adaption of Flashpoint.
It's been suggested the Scarlet Speedster's film will either reboot or retcon certain elements of the DCEU. If it's true, it'd likely be elements and aspects of the current franchise that Warner Bros. wants to distance themselves from by using The Flash's time-travel. The idea that a Justice League 2 would happen as a continuation of the 2017 film is impractical and a big step backward due to its history and controversy. If a Zack Snyder's Justice League 2 can't happen, then there's no logic in doing a follow-up to what was released in theaters by Whedon. The only scenario where Justice League will stand again is through a soft reboot that would have to be set up by The Flash or creating an entirely new DC cinematic universe as part of their Multiverse strategy.
