Notch said that Minecraft would not only be released for the upcoming PlayStation 4 at launch, but also to the PlayStation 3 and PlayStation Vita (PS Vita). We don't have much information at the moment, but we assume that 4J Studios (the company responsible for bringing Minecraft to the Xbox 360, and soon, the Xbox One) will be handling the PlayStation ports as well. We will update you when more information becomes available, but not before I stop dancing.
