According to a report from Kotaku, Activision recently pulled Sledgehammer Games Call of Duty project from development and Treyarch will now be handling next year's CoD game.
Unofficial reason is due to lingering issues with the game's development and constant bickering between Sledgehammer Games and co-developer Raven Software over its direction.
Treyarch reportedly also got really upset over the new since now they have to deal with the fallout of Sledgehammer's game being dropped and likely rush development on their own CoD game due to now having one less year to work on it.
