Worried about playing your Wii U games with that big screen controller all the time? Have some jealous friends who don't want to use Wii Remotes for asymmetrical multiplayer? Nintendo has you covered with the Wii U Pro Controller.
The Wii U Pro Controller is more standard in form than the main Wii U GamePad. There's no touch screen and it has all the functions you'd find on a standard game controller: four shoulder buttons, two analogue sticks, four face buttons. From the looks of things it has a USB slot in the top, most likely to allow charging.
There's definitely no excuse for a lack of traditional games now.
