Seeing as Heroes Season 3 hasn't finished in America as yet, it won't be released too soon. However if it follows the trend of seasons 1 and 2, it should have an American release date in August/September about a month before season 4 airs.
Tonight season 4 debuts... It would seem like 5 since they covered 4 previous storylines
