Update: A Facebook post on Xbox Singapore confirms the image to be fan-made.
Original story below as follows
Play Asia has put up an early listing for a supposed official custom Final Fantasy XV controller. The controller is not available for pre-orders as of this moment and no price or date has been listed as well. Please note that this is not a confirmed listing as Square Enix is yet to come out and reveal any video game related accessories for Final Fantasy XV. We will update you when we receive more details on the controller.
