Well, the next Wonder Woman is set in the 80s, and Aquaman is also set prior to JL. These are the solo movies that should have been made before BvS and JL. But WB/DC couldn't be bothered to set up their CU, so rushed through a couple mediocre (at best) set up films, and are now going back to the individual characters.
DC is a dumpster fire. They have no clue what they are doing.
WB would be better off shelving them entirely for a few years and find someone like Feige to run the DCEU and keep the rest of the suits elsewhere.
