iOS 7 includes new support for game controllers, and something called "inter-app audio," reports observe. The controller support was referenced briefly in a slide during Apple's WWDC keynote, listing "MFi game controllers" as an iOS 7 SDK feature. "Made for iPhone/iPod/iPad" is Apple's official certification program for iOS accessories and peripherals. Images of controllers also appear in the iOS 7 Developer Guide; the diagrams bear similarity to the look of Nintendo's 3DS handheld and Wii Classic Controller.
