Speaking to VideoGamer.com at the Leipzig Games Convention last month, Sucker Punch game director Nate Fox has revealed it's highly likely we'll see another Sly Cooper game at some point in the future.
"... we only make one game at a time, and we all really focus on it. Right now we're making Infamous," said Fox. "However, we all really love the Sly franchise and would love to get back to Sly."
Fox noted that the current PS3 user base doesn't suit the Sly Cooper franchise. "Right now, in the lifecycle of the PlayStation 3 the people that own them are largely adults. As we get deeper into the lifecycle more kids will have access to them. It makes sense for us to do an adult game or a teen rated game earlier on," he explained.
He concluded: "I can't imagine that I won't make another Sly game in my life. It's really fun."
