We're just hours away from the first keynote speech of Facebook's F8 event where we're expecting to hear about all kinds of things, including its mass-market standalone VR headset. Facebook showed off early standalone VR work with "Project Santa Cruz" two years ago, then last year revealed the Oculus Go and its $199 price. We got some hands-on time with its comfy wireless experience at GDC recently, but now Amazon watchers Wario64 and the Tracker App note that Monday night it became ready for pre-ordering.

If you're already sure you want one of the headsets that will bring a VR experience without requiring any help from a PC or phone then you can go ahead and get in line now. The only issue remaining (other than any idea about details or software support) is the release date, which Amazon has filled in with a likely placeholder of December 31st.

Update: After debuting at F8 earlier today, the headset is now officially on sale, and you can read our review right here.
