The release of the Konami-published PlayStation Vita game, Silent Hill: Book of Memories, has been delayed. The action-oriented game from WayForward Technologies was originally set to arrive on March 27, 2012, but now both Amazon and GameFly are listing it for May 31.
Konami confirmed the news to RipTen in a brief statement that offers no additional detail. More will be revealed in a formal announcement, presumably soon. For now you'll have to tide yourselves over with the recent console releases, Silent Hill: Downpour and the Silent Hill HD Collection.
