As an alternative to the recent announcements by HP and Oculus,
Valve announced its own branded headset, which they are calling Index This headset will be manufactured by Valve, Inc. itself (i.e, not in partnership with another hardware company like it did with the Vive or Oculus is doing with Lenovo on the Rift S).
