It's interesting seeing the reactions to this.
Let's be clear- despite the reactions from many here, this was not an obvious, laughable fake. There's no obvious signs of Photoshopping or image manipulation, and the concepts behind the purported controller are pretty believable as to a path that Nintendo might be going down. Until the exact frame from the UE4 demo was pulled out and compared, there wasn't really any smoking gun for either side, and even that's not a total slam dunk (although, on the balance of probabilities, it does make me think that it's fake). I'm inclined to think that a physical model was built based off the patent imagery, and a believable-looking screenshot was Photoshopped onto it to add credibility. If that is indeed the case, this is an incredible fake, with a hell of a lot of time, attention and detail put into it. However, people leapt onto it and called it an obvious fake because of their disbelief over the concepts shown, rather than the actual execution of the picture itself. Considering how little we know about the NX's overall direction, that's more than a little silly.
