A Wonder Woman game is in development at Monolith Productions, it was announced at The Game Awards. That's the studio responsible for Middle-Earth: Shadow of Mordor and its Shadow of War follow-up. Like those games, it'll be published by Warner Bros.
Aside from those details there's not much else: the announcement was comprised of a 30 second teaser trailer, which you can see below:

Anything resembling a release window or actual gameplay footage is probably a long way off, given how brief this teaser was. Likewise, it's unclear whether the game will tie closely in with recent portrayals of Wonder Woman by Gal Gadot, or if it'll strike out on its own path.
Wonder Woman will be Monolith Productions' first game since the release of Middle-earth: Shadow of War in 2017. Before the Middle-earth series, Monolith was best known for the F.E.A.R and Condemned games.
