POIs will continue to be upgraded or added. I think we are done adding new world model art for now. We're focusing on bandit modeling, upgrading trader art and zombie art as a lower priority.
Right now the roadmap I'm involved looks like this:
Dec: New books, Perk reduction (making many 5 rank non combat perks 3 ranks)
New candy items for vending machines, which will reduce food some in vending. Candy boosts attributes and skills and is not food.
Jan: Vehicle mods and crit system for vehicles and players.
Feb: Legendary items.
March: Testing/Balance.
That is just me specifically, other people are working on stuff, like DMS, POIs, quest improvements, new quest types, etc.
