FWIW, it went to Preparing for Shipment in the early hours (for me) of Saturday, Jan. 12. Listed as Shipped on Monday, Jan. 14. Apple said it'd be delivered on Thursday, Jan. 17, but FedEx said Wednesday, Jan. 16. I checked tracking on Tuesday morning and it showed as having gotten to Memphis, then to Boston, then back to Memphis (???), but it showed up at my home in MA only a couple hours after that and the tracking info on FedEx had all been corrected. Long story short, it showed up a day earlier than even FedEx had listed. Glad I was working from home to get it!
