It would kind of suck if we lost Cavill but kept Miller.
The optimistic reading would be he shows up to announce something and they want it to be a surprise...
I noticed Ray Fisher isn't there. I'm guessing the recent accusations against Whedon and Johns may be a factor.
I can kind of see why WB wouldn't want someone who badmouthed their production (however justified) to show up for their big convention even if he is excited for the Snyder Cut.
I wonder if Miller being there means we'll get more concrete news on the Flash movie (beyond him still being, well, The Flash). Actually if Kilmer's there maybe he is the Batman for Flashpoint?
I'm surprised Momoa isn't showing up (unless he just hasn't been announced).
