As far as landmass goes all that's left to be added is an area in the sky for angels, there's still quite a bit of unused space already so that will be utilized. The UI isn't final and neither are the board quests, more areas are planned to have locked gates as well which is currently what is under development. Traits are also not final, it's still being decided if wild ones will come with traits or not as well as items that modify traits. There are still more hybrids and wild nephelym planned along with more animations and the hybrid system itself may be changed. Many, many more blessed ones are planned. Breeding may also change as well because of how breeding tags work, it's still too restrictive on what you can create but this depends on if the developer can come up with something that works. More hair/clothing/decor options as well as an option to change them after character creation, more penis styles that can be "equipped". Implementation of the various stats as well as willpower affecting surprise sex along with a new "minigame" for surprise sex. AI needs work too.
It's still a long ways off, I try to keep a positive outlook but you'll probably want to give it a couple more years minimum and to be frank that's being very generous.
