I'm just taking a guess, but from what i can tell it seems like it all depends on your location and your nearest Apple distribution center. I'm guessing that when you place an order your order is sent to the nearest store and put on queue list, which explains why some get long wait times and some get instant. My guess is that if your out of the country you get it sent from the nearest country that has a distribution center. This might also explain why some people even in the USA get long wait times if that center also happens to be doing alot of international shipping. If i had to guess i would say that the USA center's handle most usa orders and China handles most of the rest. If their are any apple distribution centers in your country then you might be on a big wait list if their arn't that many.
