As forewarned, Oculus VR is officially ending sales of its first-run development kit. "We're quickly running out of stock for the Rift development kit, so we've shut down sales in most regions," a note from Oculus says. Specifically, the issue comes from certain pieces of the headset "no longer being manufactured." That said, those headsets are more than a little long in the tooth at this point: both the HD version and the Crystal Cove prototype take giant leaps past the first dev unit, to say nothing of Valve's prototype. Oculus isn't offering anything official in terms of word on new dev kits (beyond what the company's CTO told us last year), but we expect many devs already have some form of new hardware from the fast-growing VR company.
