We heard a while ago that Defense of the Ancients creator Icefrog had been hired by Valve to work on something that would make DotA fans excited, and now voiceover artist Jon St. John – better known as the voice of Duke Nukem – has tweeted that he visited Valve in Seattle to do some "recording for DotA." Interesting. There have been a few DotA-style games released already, including the popular League of Legends and Heroes of Newerth, but if Valve's collaboration with Icefrog is actually called Defense of the Ancients, it could be even closer to the classic game than any of the full-scale competitors.
Of course, the original DotA was a WarCraft 3 mod based on an original StarCraft map, but with Valve on board, this would presumably be a standalone title with plenty of Icefrog insight. We've contacted Valve to see what's up and just how close that announcement might be, and we'll let you know if and when we hear back.
