I'm trying to figure out whether or not David Goyer's original statements that Krypton is set in the DCEU remain true. Does anybody know one way or the other?
Not for sure, but I'd say the involvement of present-day characters like Adam Strange and Brainiac, not to mention the reported involvement of some version of Doomsday, makes it unlikely. It will probably have certain elements in common with the DCEU while not being in precisely the same continuity -- which is what has historically been the norm for TV series spun off of movies, like Planet of the Apes, Starman, Alien Nation, or Stargate.
