He's been too big of a headache already lol and if Keaton is now out as the standing Batman in the DCEU and they are planning on just starting everything over anyway what's the point of releasing flash? They won't work with Miller again, they are going to release Shazam, Black Adam and Aquaman 2 because they likely have a shot at making decent money and they also want to preserve the relationships they have with the major players in those films. I've seen some rumors today that Aquaman may get moved all the way to December of next year and that Shazam may get moved as well.
