Nintendo Switch to have VR: the gamepad is also a VR screen.

[Pyro as Bill]

The Switch doesn't have to be strapped to your head, it could be attached to your belt or worn like a man-bag and still be more wireless than other offerings.

The Switch screen doesn't have to be the screen(s) used in the VR headset.

A VR addon that included a VR headset and a second Switch would be more powerful than PS4VR and it would have Nintendo software.
