No, go read the FedEx service descriptions. IP Direct packages are treated as Standard Overnight deliveries as soon as they clear the customs checking at either of the two primary distribution centers. In most situations, shipments coming into the US (since they are bulk palletted air-freight) ship to the distribution hub in Memphis, TN (Shanghai to Anchorage to Memphis). They are broke down and checked through customs and shipped out. As soon as they are cleared for shipment, they are treated as Standard Overnight service from Memphis TN to their next destination within the USA. For Canada and Mexico deliveries, this changes to the proper respective services - usually adding a day or two. From Memphis, not all US cities are served by Overnight delivery so some places take an extra day.
But as far as Apple's options for shipping via FedEx go, the only two choices to ship from Shanghai to the Customer are International Standard Direct and International Priority Direct. IPD is what they use regardless of which shipping option you choose. ISS is similar, but is typically treated as gound delivery once it clears customs. Apple doesn't use ISS.
Anyway, take that as you will... But I ship enough stuff internationally both in and out of here and have ordered enough systems from Apple and others that come direct from Shanghai. FWIW, I've ordered an MBP, 4 G2 shuffles and a Nano in the past few weeks and all of them with standard shipping. All originated from Shanghai and Suzhou and arrived to me in less than 40 hours transit time -- or accounting for the 15 hour time difference between me and Shanghai, right at 2 days.
