That reminds me of something what I shared a few months ago.
The 3D headset, where the system is wireless connected to the headset, giving you the nice stereoscopic 3D environment (like 3DS) within a headset, but where others can enjoy your gameplay by looking at the system's screen or TV.
You could say: Yo, why not intergrating VR in it, instead of just 3D? Well, with just stereoscopic 3D, the basic but strong traditional gameplay and controls would still exist, while that would be different with VR having all kinds different controls. I did play some VR games in a friends house a month ago (Amogus VR and Carve Snowboarding demo), and it was fun, but I still like to stick to traditional controls via a Pro Controller.
