Until Dawn, my own personal Game of the Year for 2015 was a surprise hit for Supermassive Games despite near non existent marketing from Sony. Sadly it looks like we won't be getting a sequel any time in the future.
In an interview with Gamesindustry.biz Pete Samuels, Supermassive's Manager Director revealed "There's a lot of speculation about what we're doing and what we're working on right now....we're not working on Until Dawn 2 at the moment. We're working on other things."
Supermassive are currently busy working on several virtual reality titles, including a jump scare filled spin-off called Until Dawn: Rush of Blood which is slated for release in October for Playstation VR.
