Rob Pardo, the Executive Vice-President of Game Design at Blizzard, has added a tanker load of fuel to the flames of an ongoing rumour that a next-gen MMO project is in development at Blizzard.

Speaking to German site OnlineWelten during the recent Blizzard Worldwide Invitational in Paris, Pardo answered questions regarding job postings on the Blizzard website for a next-gen MMO that turned up last year.

After being asked whether these job postings were for Diablo III Pardo said, "No, obviously not, because it's not an MMO," before adding, "We have another development team that is very early on..."

Pardo was then asked whether there was still one unannounced project after Diablo III, to which he replied, "Yeah, there is still one "unknown" project."

This strongly suggests that the sole remaining unannounced Blizzard project (after Diablo III was revealed at the weekend) is this next-gen MMO project that turned up in last year's job postings.

Feel free to start guessing exactly what this project might be on our message board below. The most entertaining suggestion wins a ball of yarn.
