It’s most likely that Patty Jenkins is referring to the still-developing Wonder Woman 3 and the Amazon-focused spinoff series that would be “part of the in-world story of Wonder Woman.”
Jenkins has spent the last four years investing time and energy into giving Diana Prince a fulfilling live-action outing with WW84 in addition to her script for the third film. Jenkins and Gal Gadot have developed a great rapport that goes beyond the confines of the Wonder Woman franchise, and both of them only want to continue the series if they can do justice to Diana’s on-screen legacy.
In a recent interview with Entertainment Weekly, Wonder Woman 1984 Patty Jenkins expanded on the mystery of what comes next for Gal Gadot’s Amazonian princess after her solo sequel. She reveals that she has “two more stories” that complete the saga, but she is not sure if she will direct them herself:
The story continues after this in movies that I may or may not direct, but I have two more stories that become the completion of this story and it’s all about women stepping in as women, in the most loving kind pure and natural way. And making a difference in the world without having to change who they are to do it.
