Veteran Call of Duty voice actor Billy Murray is claimed to have confirmed work on Modern Warfare 4 in a meeting with a fan yesterday.
ThisisXbox.com writer Jason Andrews met Murray - voice of Captain Price - on a flight from Bodrum to London, posting the photograph seen on this page as proof.
Murray is quoted as revealing during a conversation: "On Monday I am off to meet Infinity Ward about the next game, Modern Warfare 4, I'm doing work on the sequel to Modern Warfare 3, it carries straight on and I only ever appear in the Modern Warfare games..."
Activision was unavailable for comment at the time of publication. Further comment is being sought.
Earlier this year a CV belonging to an Infinity Ward engineer suggested the studio's next game will release on both current and next-gen consoles.
