Alright, so according to their Trello and everything that's going on, I think that's what we will get:
1) Addition of 3 or 4 new items (bear meat, bear traps, berries, bone fragments, bone knife)
2) New GUI
3) Bug fixes like barricade + pillar exploit, airdrops and no clipping wolves and bears
4) Addition of dynamic resources, not always in the same place
5) Scale gameplay elements based on population
Edit: but I still hope we will get some actual new content.
This is what I'm definitely hoping for.
ALSO have you seen their art section in their Trello? Tom Butters is working on some new models that look amazing.
