I wonder if it really matters that much weather you ordered it earlier or later as long as you ordered it in a sertain period. With these large numbers they probably create separate batches for example the whole of Newyork will be a single batch
But im only guessing...
We can probably say for sure that there are at least 3 distribution centres (Americas, Europe, Asia) but maybe more. The factory sends out batches to the distribution centres and they will process them and send them to "developers". Each centre will have a list of deliveries to make in first come first severed order.
If in Europe for example the number of orders before yours is quite low then there is a good chance you will get one quickly. Purely depends on the number of orders though, just using it as an example.
If you live in the states you're probably behind a bung load of people as there will be more orders that side of the pond.
