And just as we said no international braodcasters had given firm airdates, a report comes in that HBO Hungary has promised they will make attempts to air the show the very day after the American premiere. That would be April 18th. The original blog post can be found here. The key quote, as provided by Google Translator, is:
From what The Rabbit and ipopic tell us, HBO Adria also showed The Pacific the day after its U.S. air date. This gives not only Hungarian fans, but possibly fans in the Balkan areas covered by HBO Adria, a serious boost to their hopes to see the show only very shortly after their lucky American and Canadian compatriots.
Latin American fans, how has HBO Latin America aired programs in relation to the U.S.? This could provide a hint as to when the show will premiere in your country.
