Wonder Woman director Parry Jenkins has been signed to direct the sequel (for a Dec 13th 2019 release). According to the Hollywood Reporter story she gets oodles of money upfront & box office gross (better than BO net, which with studio accounting can be zero).
In related news the Wonder Woman Blu-ray & DVD discs are available starting today, Tuesday the 19th, in outlets such as Target, Best Buy, and Amazon. According to a review in Batman-news the disc has lots of extras.
To publicize the disc availability Warner Bros. had a 300-drone display light up the Los Angeles early night sky with Wonder Woman images. See the following for the show.
