Looks like the month of Silent Hill won’t be completed after-all, since Konami has confirmed that the Playstation Vita title, Silent Hill: Book of Memories has been delayed.
Silent Hill: Book of Memories was originally scheduled to release March 27, 2012, but Konami confirmed to Ripten that the game has been delayed. No new release date has been announced but retailers such as Amazon and Best Buy are showing new placeholder dates.
