Monolith:

Following Shadow of War's release in 2017, Monolith was not interested in making another LOTR game and began developing an original IP codenamed Legacy. After Legacy was cancelled by WB in 2021, Monolith's entire leadership team and many other devs quit. Most of these devs went on to form Cliffhanger Games with EA, and are currently developing a Black Panther game.

Monolith then began work on Wonder Woman around May/June 2021. The game would be revealed at the Game Awards 6 months later. Monolith was forced to work on Wonder Woman while simultaneously rebuilding their staff and leadership team.

During development, a debate emerged about whether to use Monolith's in-house engine for Wonder Woman, or switch to Unreal Engine. They eventually decided to stick with the in-house engine, but often ran into problems as many of the programers and engineers who knew how to properly utilize the engine had already quit.

Around late 2023/early 2024, Wonder Woman was completely rebooted. The game changed directors, the Nemesis System was removed, and the game was changed to be a more traditional action-adventure game similar to God of War.

Monolith devs had no beforehand knowledge of the studios closure. They learned about it on Tuesday, shortly before we all did.

WB Montreal:

Following the release of Arkham Origins in 2013, WB Montreal began development on two games: their own Suicide Squad game and a sequel to Arkham Knight focused on Damian Wayne. Both were eventually cancelled, and they began developing Gotham Knights in 2017.

Gotham Knights was originally intended to be live-service, but they reversed course. According to Schreier, the game itself wasn't changed much by this, it was more like WB just decided to scrap the post-launch plans.

Schreier says the "Gotham Knights 1.5" he mentioned previously in his article would have actually been a separate, smaller game like Spider-Man: Miles Morales, but it wasn't approved. As he also mentioned in the article, WB Montreal pitched a Constantine game that was never greenlit, and then began working on a Flash game that was cancelled after the movie flopped.

Following Gotham Knights failure, some execs at WB Games wanted WB Montreal to become a support studio, and many devs were put on support for Wonder Woman and other games. As of now, WB Montreal is currently pitching a new game based on Game of Thrones.

Other WB studios:

Schreier reconfirms that Rocksteady is in early development on a new Batman game.

As was previously posted on this sub, TT Games is working on a new Lego game that is planned to release next year. He doesn't say exactly what it is, but there have been rumors that it's a new Lego Harry Potter that adapts the whole franchise in the same vein as Lego Star Wars: The Skywalker Saga.

As previously reported, Avalanche is working on a Director's Cut of Hogwarts Legacy with new DLC; many Rocksteady devs are also working on it. Avalanche is also in early development on Hogwarts Legacy 2, but that's still a long ways off.
