Silent Hill's debut on the PlayStation Vita — Silent Hill: Book of Memories — will not hit its March 27 release date. Amazon and Gamefly both have given the game a May 31 placeholder date, and Konami confirmed the delay to RipTen.
The game was originally slated for a Vita "launch window" release, and the handheld arrived in North America last month. So the May 31 date means the title has probably been moved out a quarter or so.
Konami told RipTen "a more formal announcement" is forthcoming
