While Diablo III will not be released any time soon, it's comforting for anyone looking forward to the game to know that Blizzard has given its assurance that Starcraft II's delay will have no significant impact on the schedule of the company's other games, including Diablo III.
Blizzard president Mike Morhaime addressed the issue at the company's quarterly earnings call and reiterated the company's plans to release one major game per year, emphasizing that we can hope to see two games released in 2010.
