Robert Bowling has revealed that Infinity Ward is not "tied to making Call of Duty games", and in the future may possibly create something else should the franchise "stop being fun".
"Once this is done, maybe we'll see about doing something new," he told Develop. "If we do want to do something else, then we will do it.
"We don't feel tied to making Call of Duty games.
"We still make Call of Duty games because we're having fun doing it. And when it stops being fun, we'll move onto something else."
Modern Warfare 2's out this month, just in case you've been trapped in a cave someplace and are just now escaping.
