Though we don't yet have an official word from Konami, it's starting to look like Silent Hill: Book of Memories for PlayStation Vita has been pushed back to October 31, 2012.
Amazon listed the delay earlier today where it was spotted by a Destructoid reader. It's not unanimous yet though, for instance GameStop still lists Book of Memories as arriving on May 22, a mere week away.
Konami themselves have remained mum on the issue, and have not announced a delay of any kind. Then again, they didn't announce a delay the last time Book of Memories was pushed back, either.
If nothing else, it'll be nice to have a Silent Hill title on Halloween. Hopefully they're using all this extra time to enhance the game, and it's not just lying on a shelf somewhere at Konami Headquarters.
