It's not a confirmation but why the heck do they need a "PlayStation 3 Specialist" if…? You get where I'm going with this.
There have been a lot of rumors that Blizzard would bring the long-awaited Diablo III to consoles and now, there's a very strong indication that it'll happen. There's a job listing at the studio's job portal; it's for a Senior Software Engineer with prior knowledge of Sony's machine. Part of the description reads: "…responsible for overseeing PlayStation 3 (PS3) architecture design, as well as other PS3-specific game code development to maximize platform performance." Well, that's self-explanatory. Last year, Blizzard was looking for a lead designer for "consoles" so it seems clear as crystal: Diablo III will be coming to consoles, or at least the PlayStation 3. Unfortunately, the game still appears to be a ways off.
And at the rate this project is going, we don't expect fresh news any time soon. But who knows?
