Don't forget that they are all playable and can be picked as your character (or your companion character). So like D:OS2 all companions are tied to Nautiloid. I do wonder if they will revise opening before 1.0 to include more future companions, like D:OS2 did.
So far we indeed dont have any, nor any indication that there will be possible companion that isnt aswell origin character ...
But what would stop it? O_o
I mean except Larian dont wanting that ofc.
