Update: Infinity Ward has denied meeting with Murray about Modern Warfare 4. "Interesting news today, but it's not true," said the developer on twitter. "We've not talked with any voice actors, so all news is speculation."
Original story: Modern Warfare 4 is unsurprisingly Infinity Ward's next game, according to Bill Murray, the actor who voices series stalwart Captain Price (and no, he's not that Bill Murray).
Murray leaked the confirmation to This is Xbox after unknowingly sitting next to one of its editors on a plane.
"On Monday I am off to meet Infinity Ward about the next game, Modern Warfare 4," he said. "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…"
The next Call of Duty game, Black Ops 2, isn't even due until 13th November, while a Wii U version will coincide with the system's launch. Historically Infinity Ward switches off with Treyarch to produce a new entry in the series every November, so it would make sense for Infinity Ward to release Modern Warfare 4 in November of 2013.
