Blizzard rarely, if ever, provides release dates for its games before it's ready to do so, and as such, we still have no indication of when Diablo III will finally be out. It's been a decade-long wait for a Diablo sequel, during which time a very different version of Diablo III was created and then canceled. We might be nearing the end of that very long wait as director Jay Wilson has suggested the game's development is approaching the end.
"We're definitely in the home stretch. We're crunching," Wilson told the New York Times. "This is when the magic happens." It's a vague statement and Wilson wouldn't commit to nailing down even so much as a year, let alone a date. Knowing development is in the home stretch, though, lends credence to the idea that it could still make it out by the end of 2011. Blizzard has said in the past it's avoiding the announcement of a release date so it's not forced to rush development and risk the game's quality.
Blizzard hasn't ruled out the possibility of a new game coming in 2011. It's not a certainty, either; the company has only said that it expects two games out in 2012 if nothing ends up releasing this year. Those two games would presumably be the next chapter in the StarCraft II trilogy and Diablo III, but after waiting 10-plus years for a new Diablo, it's best to not take anything for granted. A new World of Warcraft expansion isn't impossible for 2012 either given that Blizzard has indicated it would like to see expansions packs released more frequently.
