Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General 4 hopes for DOS2

In D:OS classic, they had partial voice acting as added flavor for certain NPCs (if I'm not mistaken) the cheese vendor being one of them.

It is not inconceivable that they take the same approach for D:OS 2 as these lines would not be affected by the multitude of the players different choices. (They are independent of the tags system)

That being said no official word has gone into detail about flavor dialogue being voiced. (Shopkeeps yelling about cheese, fish etc)
The problem, as you can see by the original poster, is some people did not like that aspect of the game so there is no guarantee that it will remain in D:OS 2.
