Dammit. There have been rumors of Rocksteady working on a new Superman game for quite some time, and now it looks like those rumors are bearing exactly zero fruit. This is what Rocksteady Studios game director and co-founder Sefton Hill had to say about the rumors in a tweet last week.
"Looking forward to #TheGameAwards this year! We’re still hard at work in our development bunker so don’t expect an announcement from @Rocksteadygames. When it’s ready to show, you’ll be the first to know. Spoiler: it’s not Superman."
