Guesses can be made about this CUlt of the Wolf

There are Werewolves in the Mountains, maybe those will be "part" of the Wolf CUlt in the relevant update?

Seeing that they want to make procedurial generated Caverns and Dungeons in the Mountain biomes to have more to do in it, it could be something.

There is also the tweaks and reworks for combat,n that they started to make with Hearth & Homes update

Updated Ocean biomes with more things to do and more creatures

Addition of the last 3 Biomes, Ashlands, Deep North and Mistlands, with each their assortement of new ressources( so new receipies and materials to craft from it), new mecanics/building materials and new enemies/Bosses.

For a total of 9 Biomes with 9 Bosses, and the possible inclusion of Mini-Bosses.

And whatever smaller updates they might cook up to add some new things to the game.

So we still haven't seen the end of it for now.
