Regardless, they are a decent concept controller design

On Wednesday, a Reddit user posted two images of an alleged Nintendo NX controller prototype in what seemed like a very convincing leak of the company’s next-generation console controller hardware. While the shape of the controller in question very closely resembles patent applications that Nintendo has filed in the past, the images have now been verified by their original author to be a hoax and were the creation of his 3D printer and a simple computer model.
