The man behind the voice behind reoccurring character Captain Price, known IRL as Billy Murray, unwittingly told a member of the press about the existence of Call of Duty: Modern Warfare 4 while chatting on a plane.

The fact the game is at least in pre-production stage isn’t the biggest surprise but it’s certainly not officially been announced.

"On Monday I am off to meet Infinity Ward about the next game, Modern Warfare 4," he told Jason Andrews, an editor of This is Xbox. "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…"

Call of Duty: Black Ops 2 is coming November 13 on PC, Xbox 360 and PS3, its Wii U counterpart arrives November 18 on the same day the console releases.
