I don't believe so. We currently don't have that good real time translation softwares about, and the language barrier is something we, the users have created. It is an international game after all, english is commonly used then. Then you have people not wanting to use english, so they'll huddle in to guilds of their own country/language. Only way a fix would be is a real time translation, though wont be in the near future to get one that works correct enough.
Blizzard offers support of selected languages, from there on, I don't think they should do more. Just means more translators needed.
