According to @evleaks, what you're looking at here is a forthcoming iPhone gaming controller from mobile peripheral purveyor Moga. Like the simpler Logitech leak we saw before, the new controller mimics one of the reference designs released by Apple in the documentation for iOS 7.
Even more images reveal that the rumoured Moga controller above will be called "Ace Power Controller" The also give us a sense for the thickness of the gadget, which will have some thickness to it, In a good way.
The leaked hardware has a more angular, easier to grip design than what we saw before; it looks a bit like someone stuffed an iPhone inside an Xbox controller. Thumbsticks could really change the way you play some games. And if @evleaks is right about the 1800 mAh battery built into this thing , it'll change the way you play by making sure you never have to stop. [@evleaks]
