I think most of folks won't wait and will play anyway but without paying. Well I can't say I blame them because it's Larian's fault.
Well, that's kind of hypocrite, don't you agree... people in Poland want Polish translations and they want the game at huge discounts (compared to what the rest of us have to pay), and if they don't get that, instead of completely boycotting the game, they will still play the game (in English, which means Polish isn't all that important to them after all) and without paying a cent for it (ie pirated)... and on top of that, they'll blame Larian for that!
With such an attitude, it's no wonder if Larian that doesn't want to spend extra money on Polish translations...
