If the Wii U Pro controller doesn't sit right in your hands, the good folks over at Cyber Gadget have a solution for you. With their new adaptor you can throw the Nintendo made controller away and replace it with Sony's PlayStation 4 controller, the DualShock 4.
Don't throw away everything though, as you'll still need to connect the PS4 controller to a standard Wiimote to be able to use it. The adaptor is already released in Japan, and we'd be surprised if something similar didn't made it to these shores too.
Thanks, Wii U Daily.
