A small group of us are buying into the FedEx Theory... that FedEx will come to save the day, decent from the heavens and rain apple watches down on all of us.
I wouldn't discount the possibility that UPS (I won't say the word that starts with F and ends with edEx) will process product throughout the weekend, though I have no idea how Apple shipping and other logistics work. Usually stuff cargo keeps moving, though. Maybe someone more knowledgable can chime in.
