Since the Amazons spinoff is taking priority, it seems like we’ll have a longer wait in store for Wonder Woman 3 compared to the gap between Wonder Woman and Wonder Woman 1984.
Back in April, Patty Jenkins said the plan was for this Amazons spinoff to come out before Wonder Woman 3, so we may learn specific details about it sooner rather than later.
As for the threequel, Jenkins revealed in early 2019 that it would be a contemporary story, but as of this past June, she’d paused working on the story because she wanted to absorb “whatever the result of this pandemic is.”
