It will probably take atleast another 2-3 years since the game has a lot of ambition and systems whose foundation are added, but not with the actual content yet
Followers
different POV's from characters
Village mechanics
Alignment
Insanity/Masochism/Sadism
Harassment mechanics with different mobs
Trauma mechanics for the priestess
Etc.
Also Technobrake is working solo as far as I know, and his translator quit some time ago, so he also has to do translation by himself, which is time that could have been used to further develop the game.
