According to studio exec Guillaume de Fondaumiere, the Sony-published title was put back to early 2010 so it could be given its own release window.
"The first and most important reason [for the delay] was the fact that I don't think that such an innovative game like Heavy Rain and a new franchise should be released at the end of the year in the crowded period when everyone’s releasing their games," he told CVG.
"A game like Heavy Rain needs space, needs to be explained and shown. At the end of the year, people can't afford to buy all those games so we wanted to give Heavy Rain the chance to have its own release window, and for us to really talk about it so people really understand it."
Billed as "a very dark film noir thriller with mature themes", Heavy Rain will be released for PlayStation 3 early next year.
