Its pretty clear that despite what people were told, there was a difference between those who had standard shipping and those who either choose or were lucky enough to get a free upgrade to expedited shipping.
Standard Shipping = UPS World Ease. This is a service where the whole load is batch-cleared by US Customs. Apple will frequently use this for new product delivery. The first departure of these seems to have departed collectively from Shanghai at 10:50pm local on December 10. My guess would be that this load goes to ANC and later to SDF (Louisville) and they enter the UPS system near the end of this week for delivery by next Tuesday or so.
Expedited Shipping = Fedex Express International. This has a 3 business day transit time from China, where Fedex picks them up, and sends through their typical channel (flights to Tokyo, Oakland or Memphis is most common) and they are delivered perhaps as early as Wednesday but likely Thursday or Friday to those who have this service.
Wish I had convinced Apple to give me expedited, but at the end of the day I'm still happy my 2.9 Ghz with 1TB Fusion ordered at 12:05am Pacific via the EDU channel shipped today, at least a week earlier than I'd expected.
