I'm all for a redemption arch, so if Snyder ends up doing something like the Authority or his dream project, The Dark Knight Returns as an Elseworlds movie, then I'm down for it
as long as he's kept on a short leash especially when it comes to the script. For all it's faults, Man of Steel is one of Zack's most inspired efforts partly because of the lack of slow mo but it seems the more freedom he's given the more he leans into the things that turn off many fans. Who knows? Maybe another Gunn/Snyder collab is exactly what Zack needs to shake off his current funk and restore good faith in fans who have soured on his style, like myself. But whether or not he'll be able to swallow his pride and work under Gunn after having significant control of the DCEU and total control of his own universe, that I dunno.
As for whatever the announcement is next week, I'm tempering my expectations. I got excited for some potential footage from the puppy bowl but the best thing we got were those clips of Guy Gardner.

I feel like next week's announcement will be something we already know or suspect.
