Blizzard has been developing various iterations of Diablo III for a decade now, but game director Jay Wilson is assuring they're "in the home stretch."
"We’re crunching," he says. "This is when the magic happens.”
A 2011 release, perhaps? Fans can hope.
Part of the reason for the lengthy development time is the game's "virtual economy", a trading post of sorts for weapons and such that sounds like it'll be far superior to what you saw in Diablo II. Though no specific details are known yet, it's implied the new system will be far more user friendly.
