Also pre-ordered on Amazon on 9/11. Still shows “Order Received,” but saw that someone on Reddit said they finally received an Amazon confirmation with an estimated delivery date of the 19th.
I tried pre-ordering them at Seattle Best Buy for store pickup and it says "This item is no longer available for the delivery method you selected." so my guess is that Best Buy won't have them soon. Apple stores here say between Oct. 2 and 9.
