Speaking with CNBC, the Sony head said: "Personally, it's very difficult for me to perceive God of War 3 being played with the Wii controller," he said. "It's a different experience that doesn't lend itself to certain types of games. [But] I think our [motion] controller can be used with every game that's on the system now - and every game we're working on."
When asked whether the controller could be compatible with current PS3 games he claimed it "absolutely conceivable." It's interesting the stance Sony appear to be taking with their motion controller, Sony apparently want to make current games feel more visceral.
