The thing is, ultimately this argument is Larian claimed they'll do it, and you are claiming they will not. It is possible they'll change their mind but very very unlikely. Everytime they said if they'll add stuff they said the PHB first, though notably Swen said they are holding back some stuff from EA so the final release feels even more substantial. I have every confidence they'll implement all 40 subclasses of the PHB, they have the team and resources. And I am confident they'll implement every subrace. To not do that would border on false advertising AND would be quite disappointing considering they have the team, resources, and time to translate way more than just the PHB to BG3.
