While today's new Apple TV reveal talked about games, it didn't talk about traditional game controllers, instead choosing to focus on the device's remote control and how it can be used for game input. But a screen of the App Store listing for Supergiant Games' Transistor, which came to iOS earlier this summer, had a curious listing: "Game Controller Optional." The iOS release of Transistor already supports iOS-compatible gamepads, so it stands to reason that those same gamepads will work on the new Apple TV and its tvOS. The Apple TV release also supports any existing game purchases that you already have on iPhone or iPad.
Those existing iOS-compatible controllers include offerings from familiar brands like MadCatz, Steelseries, Logitech and Razer. Many of these controllers are built to be portable, or shells for the iPhone itself, hardly optimized for the living room experience Apple TV aims for. Without an announcement at today's event, it seems unlikely Apple is making its own game controller but we'll ask Apple to clarify controller support on the platform.
