Game's been in development for 6 years, only around 16 or so enemies done or near finished. Roadmap says it's going for 50 or more enemies plus some other things that aren't implemented yet. Math says it will be a very long time.
We have sculpts done for over 30 new enemies/characters, rigging and low poly done on two thirds of those and combat animations complete or in-progress on over 10.
So long time instead of very. May be a few years still though. We shall see. Unless you have been drip feeding the content for the sake of milking the game. Then it will still be a very long time.
