Quantic Dream's David Cage has told VideoGamer that there's still more that can be done with PS3.
When asked if Heavy Rain was pushing the limits of the console, Cage explained that there is still much more that can be done with PS3.
"You need to keep in mind that Heavy Rain is our first title on PS3," he told the site. "It's not the second or third generation of games on the same platform. We've just discovered the platform right now. So yeah, there's plenty of room for improvement I'm sure.
"At Quantic Dream we know we can do much better than what we do here."
Game's out early 2010.
