A Sony representative has confirmed to us that Heavy Rain won't start pouring until the first quarter of 2010. Quantic Dream's David Cage told us that Heavy Rain would most likely get lost in the shuffle, among the Modern Warfare 2s and the Assassin's Creed 2s and that a Q1 2010 release suits the game much better.
For those anticipating the game's release this is undoubtably a disappointment, but a release during this period may mean better sales figures, which may mean more games or DLC for the series. See? Every rain cloud has a silver lining.
