Blizzard Dota, the Defense of the Ancients-style official mod that was shown off at last year's BlizzCon, is still a work in progress, according to lead producer Chris Sigaty. The other three mods shown last year were released a little while ago to the community, but the Dota mod, which pits all kinds of Blizzard franchise characters up against each other in a real-time battle, needed a little extra work, apparently.

"We basically put it back up in the shop and did some massive overhauls to some things, which I'm not going to go into specific detail about," Sigaty told Joystiq at a press event last week. "But yeah, we are working on Blizzard Dota, and we do intend to launch it at or around the time of Heart of the Swarm, but the official details will be online later."

Will the mod eventually require the upcoming Heart of the Swarm expansion to play? Sigaty's got nothing yet: "We're not even talking about the business level decision of it at this point." But rest assured that, somewhere on Blizzard's Irvine, CA campus, there are still developers fighting over who'd win in a fight, Thrall, Diablo, or Tychus Findlay.
