I'm convinced WB will fast-track an Wonder Woman sequel for 2019. Patty said she has some concrete ideas for the sequel. Not to mention she, Geoff and Allan Heinberg nailed the WW script within months after she signed on. [...] I'd be shocked if WB waited until 2020. Sam Raimi managed to turn out Spider-Man 2, widely regarded as superior to the first, within two years of the original.
If everything falls into place, Wonder Woman 2 could happen in 2019. I just hope they don't rush it unnecessarily, that's all I'm asking.
