It looks like we won't have to wait much longer to find out whether or not the next Apple TV will double as a gaming console. 9to5Mac has found references to a new model of the Apple TV hardware within the iOS 7 software build. The list of items includes "AppleTV2,1" and "AppleTV3,1," as well as the current model, "AppleTV3,2" and the upcoming "AppleTV4,1." This reference has been hidden inside of iOS 7 for months, but it was only recently discovered by 9to5Mac and developer Hamza Sood. The last hardware update from "3,1" to "3,2" was relatively minor -- "4,1" should be a major revision. There are also signs of game controller support, but there is the possibility that these are not connected to Apple TV functionality.
