Looks like it has image sensors for Amiibo/card/bar code (?) scanning, a pulse detector for ... uh detecting your pulse, and can be positioned vertically for backwards compatibility perhaps. There was also a previous patent that come out that I think was missed here about haptic feedback from the LCD screen.
