The Nintendo Switch with reinstated motion controls via VR, Virtual Realitiy, with remotes that are modelled after the Play Station Move Motion controllers.
The Wii is the console that Nintendo has always wanted to have made but never could. The Wii U was a prematureley released Switch. The Switch is like a Wii and 3DS combined, however, the motion controls are limited and optional, the games are less reliant on these controls unlike the games for the Wii. Therefore what was once there and has since been big impact, will once again be put back into a Nintendo console, however, it will be in a new revolutionary way that takes advantage of the latest technological devlopments, hence Virtual Reality controls will be implemented into the next Nintendo console.
Now that I think about it, the PS Vita was basically a preliminary for the Switch.
