Amazon says that it "does not know when or if this item will be back in stock".

The Oculus Go is expected to be released around December 2018, and will be able to run existing applications which have been released for Samsung's Gear VR headset.

The Oculus Go is also designed with a lightweight, breathable fabric so that it can be worn for hours at a time. More longer-term, though, is Oculus' decision to use 3DoF - or "three degrees of freedom" - tracking.
