In the same SEC filing that revealed that Activision was in a conflict with two senior Infinity Ward employees over charges of insubordination, Activision-Blizzard also stated that Blizzard is currently working on multiple sequels in the Diablo franchise.

“Blizzard is currently developing new games, including a new expansion pack to the World of Warcraft franchise , Cataclysm , StarCraft II: Wings of Liberty, which will be released with the new and improved Battle.net, and sequels to the Diablo franchise.”

Little more information is available at this time. Blizzard has stated in the past that it is aiming to release games in their core-franchises, including Warcraft, Starcraft and Diablo, on a more regular basis. The highly anticipated Starcraft 2 has been split into three separate instalments, of which the first instalment is slated for a release later this year. It is unclear if Diablo III will suffer a similar fate.
