Activision Blizzard COO, Thomas Tippl at Citi 2011 Technology Conference revealed that they are working on 6 “proven property” over the next 3 years. As they are based on proven properties expect the games to be part of the Warcraft, Diablo and Starcraft universes.

The likely candidates for the new games are Diablo 3 which entered Friends and Family beta recently, a future World of Warcraft Expansion or 2, Starcraft 2: Heart of the Swarm, a possible Protoss focuses Starcraf 2 expansion and a Diablo 3 expansion.

What was interesting was the fact that “proven property”, but according to Gamespot Tippl’s word choice did leave the door open for Blizzards upcoming MMO known as Titan.
