I've seen Blizzard upgraded their Battle.NET store. Going through it I can see all the licenses of the games are now language lock free, saying that I can choose any language I want from there.

Does this mean that people who bought a local retail edition with language lock got it updated to get all the languages like it was originally? Or do they still have only the language of the copy?

Also, was there ever a why for this lock?

I mean, the retail version was double the price the digital version is for Argentina, but still the more expensive version has less options. What a shame. Now after a year I'd like to know if we can finally play the game in English since the Spanish translation is horrible.
