pre-order not filled. BUT YOU CAN BUY A RIFT!!

Those may be from 3RD party scalpers though, not Amazon directly..
FWIW, I received my Rift two days after I ordered it on Amazon for the normal retail price. It came in the sealed, original packaging and has been a lot of fun to use in Elite with a HOTAS setup. It is odd that the ship date on the Oculus site last time I checked was still sometime in August.
