The engine specialists intend Unity to be the best development environment for experimenting with VR. That begins with Unity 5.1 - which features support for both Oculus Rift and Gear VR.

Thanks to Unity's new XR Interaction Toolkit, developers don't need to reinvent the wheel for simple VR and AR interactions.

More importantly though, Valve is putting the onus on hardware manufacturers to add support for the Skeletal Input system to their new controllers, and not the individual app developer.

Sony's upcoming, next-generation PlayStation VR 2 will apparently take VR gaming "to a whole new level," according to Unity.
