The Italian retail site 16Games has listed a PS3 HD collection for the Hitman series. The Hitman Triple Pack will reportedly include Silent Assassin, Contracts and Blood Money.
While the existence of the game is unconfirmed, an HD version of the games certainly makes sense. They hold up remarkably well as it is, particularly Blood Money. Man, I loved that game.
