According to Dual Pixels the Nintendo NX controller may have been revealed via photos sent to the company via Reddit.
The photo above shows the device with a nice sticky note next to it which reads “You will say wow!”

If this indeed a legitimate photo and not a photoshopped image, the device is similar to that which Nintendo recently filed a patent for.

Please note that this is a rumor so take this information with a grain of salt.

More on this as it develops.
