Well Activision today put to rest a flurry or rumors suggesting that Infinity Ward was planning on retaking the Call of Duty franchise. The rumors suggested that Infinity Ward would be the sole developer of all Call of Duty titles after Call of Duty 5, which is currently being developed by TreyArch. However, in a post from
EuroGamer, Activision assured the community this would not be occurring.
A spokesperson for the publisher told Eurogamer it was a total fabrication, and that Treyarch and Infinity Ward would still alternately create instalments in the shooter series."
