Talk of Call of Duty: Modern Warfare 4 being in development is nothing but speculation, Infinity Ward has said.

Yesterday it was reported that Captain Price voice actor Bill Murray had revealed he was soon to meet with Infinity Ward to discuss Modern Warfare 4, a game he said will be a direct sequel to the third game.

However, Infinity Ward has suggested this isn't true.

"Interesting news today, but it's not true," Tweeted the studio. "We've not talked with any voice actors, so all news is speculation."

Assuming Murray's comments have been reported accurately it's hard to believe the actor would have any reason to make up a story about Modern Warfare 4.
