NetherRealm Studios has yet to announce their progress on their next project and likely won't be doing so any time soon. There's a reason for that, though. The team just isn't ready.
NetherRealm's Ed Boon explained that they can't share anything on their projects right now.
"Really appreciate the enthusiasm for our next game and wish we were ready to announce," Boon said on Twitter in response to a fan. "But we aren’t yet. Many more variables involved than we are allowed to disclose."
As of now, NetherRealm Studios have yet to announce any official information if they're working on another Mortal Kombat or Injustice - or both.

Whatever it is, it's far from the only project coming out of Warner Bros. in the near future.
As of now, Warner Bros. Games and its partner developers are currently working on a lot of titles related to their other DC Comics and other affiliated IP, such as Multiversus, Gotham Knights, and Suicide Squad: Kill The Justice League. Meanwhile, another title, Wonder Woman from Monolith Productions was revealed at The Game Awards 2021.
