The biggest polish gaming site gry-online.pl published today information that Divinity: Original Sin 2 will not have polish localization. You can clearly see in comments that lots of Larian fans from Poland are upset by this fact. Especially when you see that few days earlier D:OS 2 won survey for the most anticipated game of September 2017 (

If you don't want to do polish localization give it to polish publishers. They have done translations and even box copies for smaller cRPG - smaller in sales not numer of words like: Wasteland 2, Pillars of Eternity, Torment Tides of Numenera (even have polish voice acting); Elex also will have full polish localization with voice acting. I know that localization cost money. But I think that gain in sales is worth it. Polish publishers clearly don't do that for charity.
