Literally no one knows, yet.

The only thing we know is there's no "genders" to pick from. You pick a male or female body, and you can have breasts on a male model, and a 'bulge' on a female model.

The model you pick determines your voice in game. And you can use any make up and hair options on all the models.

I think it will be pretty in depth, but not like, Black Desert Online in depth.
