Since Cage Match's release, there have talks about a 5th animated Mortal Kombat movie being in the works. The Fall of Edenia was rumored to be that 5th one. For the past couple of years, posts and videos about it were released on the web, but so far, there have been no updates on it.
Oh, and just so you know, I do agree with your previous comment on Legends being a tv show.
It should happen for real. It would be the perfect fit for Adult Swim and HBO Max.
