There was also no mention of a Justice League sequel, but a report from October revealed that script is already being written.
There was also a title card shown for the DCEU’s Justice League Dark movie, indicating that project is still in active development, along with title cards for Suicide Squad 2, Joss Whedon’s Batgirl movie, Shazam, Green Lantern Corps and The Batman.
The Warner Bros. presentation at Comic Con Experience began with a presentation of the studio’s upcoming DCEU slate kicked off with a title card for the Wonder Woman sequel that showed the Wonder Woman logo “flanked by Roman columns.”
Since there was no “2” in the title, it seems possible that Wonder Woman 2 may not be the official title.
