I was really hoping for the hand-held virtual portal they had planned a few years ago. Assuming it got scrapped when 3DS didn’t do as well as they hoped. But yeah, basically the tech from the *new 3DS, upgraded to a bigger single screen with an imu so you could use the portal to control the in-game camera. And it would basically feel like you are looking through and holding an actual portal into the videogame world you are playing.

It’s possible to just do more easily/cheaply in VR now. But I still think a physical device doing it would surprise alot of people.
