Heavy Rain Will Get A Playable Demo At Some Point

“We are currently working on a demo, which is a real challenge,” he said. “Finding one scene that can convey what we are trying to achieve with Heavy Rain is something really difficult.

“If we show an action scene, some players will think that this is what Heavy Rain is all about, and it is the same thing if we show an exploration scene. The problem is that each scene of the game offers contextual game play, which is something very difficult to explain and convey in a single demo. Demos are often a double-edge thing: if you don’t release one, players may think that you have something to hide.”</blockquote>

We wouldn't be surprised if they released the Taxidermist scene from last year. It has a bit of everything Heavy Rain is trying to convey, without really breaking the story as it's totally independent from the plot.
