Valve revised two long-dormant backend packages tied to as many as seven Steam Frame headset configurations, the clearest sign yet that pre-order or release-date news is near.
Those changes mirror Valve's Steam Machine rollout, when similar backend updates appeared six days before pre-orders opened on June 22 and shipments began on June 29.
Recent leaks point to a week-of-Sept. 7 reservation window and a Sept. 14 release, while dataminer Brad Lynch said on Aug. 28 that reviews were already underway and shipping should start by mid-September.
Earlier Steam client findings also uncovered ARM-app videos showing unboxing, fit adjustment and accessories such as a wireless adapter and controller straps, reinforcing expectations that Valve is preparing the launch.
Imports suggest Valve has built inventory for the headset, though the Steam Machine's slow fulfillment shows demand could still strain supply despite the product's higher-than-expected price.
