At this point, it is really just a matter of waiting to see what will happen when all is said and done.
That said, given WB’s long history with DC properties, and complicated rights deals, it doesn’t seem unreasonable to assume that the studio will continue to retain the rights and keep its development of films like Patty Jenkins’ Wonder Woman 2 and Chris McKay’s Nightwing.
It is worth mentioning that laying out this situation does not explicitly specify what will happen to some of the various Warner Bros. assets (mainly the DC Comics properties in the DCEU) if Time Warner breaks up.
