Just read over on Kotaku that it's possible to get the demo for Heavy Rain early. It involves playing a website based game - the one Sony advertised over on the eww blog. Anyway if you solve the puzzle (and the solution is provided for your convenience) then you're rewarded with a PSN code to download the demo at your leisure. By the way it's not available on the US store. That means that a whole nation of yankee doodle "hell yeah" sayers are right now stealing our bandwidth and it's a race against time people so go, go, go!
