Apple recently filed a patent for a controller that appeared online today according to Gamerevolution. This prototype device bears a striking similarity to the PS3’s controller, the Dualshock 3 and apparently is a “schematic of a video game controller” for iOS devices as well as a video game system. This controller would then be compatible with iPhones, iPads and Apple TVs making gaming on those devices a far better experience. I personally would buy such a controller in a heartbeat because my biggest gripe with iPhone/iPad games is the terrible touch-screen controls that make most action games an utter chore.
Of course like MCV observes, this design could just be a placeholder as patents more often than not end up looking different when released.
