Looks like they got a little past the winter update on that roadmap back in January and nothing since. Now this news regarding ownership of the Jason IP, probably means this game is done.

We’ve now been forced to accept that the lawsuit makes future content for the game, including alternate play modes, new playable Jasons and Counselors, and new maps, unfeasible now or in the future. Although the listed content types will be affected, we remain committed to launching dedicated servers on our console platforms and providing the continued maintenance and bug fixing important to supporting our fan base.
So what does this mean exactly? There will be no additional content added to Friday the 13th: The Game. This includes “Uber Jason”, The Grendel Map, Jason Kill Packs, Clothing, Emotes and new Counselors.
