Online gaming publication Kotaku has uncovered a patent filing from Nintendo which shows that the company was originally flirting with the idea of a 3D HD touch screen for Wii U. Nintendo’s patent filing states that the Wii U controller “might” feature a 3D display and an HD display. We already know that we won’t see the final controller until E3, so Nintendo may have some surprises in store for us.
