"We're still at the alpha stage and there's a whole lot of work to be done," said Quantic Dream's David Cage. "There's so much fine-tuning in the game left to do. Everything has to be perfect. If there's one thing wrong in a scene, it's the only thing you'll see. There are many things that don't work right now. We need to have everything in place, from facial animations, to score to work out the final result."
This is exactly the kind of stuff you want to be hearing from Quantum Dream. PS3 exclusive Heavy Rain: The Origami Killer has a release window of early 2010.
