Цитата с официального сайта:

When will Diablo III be released?

It's too early to estimate Diablo III's release date. As with all Blizzard Entertainment games, our goal is to create a game that is as fun, balanced, and polished as possible. We intend to take as much time developing Diablo III as is necessary to ensure the game meets our own high expectations and those of our players. We're aiming to release Diablo III on both Mac and Windows simultaneously in as many regions as possible, and to localize the game in several languages. We'll have more details to share about countries, languages, and specific dates as we get closer to release.

P.S. Игру вряд ли стоит ждать раньше конца 2010 - начала 2011 года.
