Further to the report below that Blizzard are expanding, Gamasutra points out that Diablo III may be heading to consoles as the company recently posted a number of positions under Diablo III for console-specific designers. Though the Diablo III community page clarified the postings.

We’re exploring a Diablo-related concept for consoles and are currently looking to fill a few senior console-related positions on the Diablo III team. As we’ve said in the past, with proper care the gameplay could suit the console platform, and we’re interested in seeing what talent out there might be interested in such a project. If you’re passionate about all things Diablo and have the requisite skill and experience, then head over to our jobs site to check out the positions and apply.

Please note that this is not an announcement of a console title. We are first and foremost developing Diablo III for Windows and Mac PCs and don’t intend to allow any possibility of a console interpretation to delay or affect the release of the game.

Interesting. At BlizzCon, AusGamers asked the 'console question' in our interview with lead world designer, Leonard Boyarski, who responded with:

"We've talked about it, I mean it's something that, you know, out of all the games that we've done as a company, it just seems like the most obvious. But right now we're just concentrating on the Mac and PC version of the game. But everyone says it, and you said it too, it's the most obvious one... but right now we have enough on our plate finishing this one (laughs)."

Take all of that as you will, but I'd venture it's confirmation we'll see Diablo in some form on consoles in the not-too-distant future.
