We all may be plane buddies - mine was origin scanned at 8 AM local, so we all seem to be right around the same time - except your guys' are so close they are on the same pallet!!!
Anyways, if you want to see something interesting, track your package by reference (your order number or 9-digit phone number). It seems that Apple sent the Shipping Info twice for some people, so searching by that will give you two different strings of package details, however everything including the tracking number is identical EXCEPT the billing info times.
My 'normal" package says 4:50 AM on 3/31, yet the "second" package said 11:50 Am local time on 3/31.
So whatever the reason, either Apple or UPS, they got the billing info twice - which may explain why it took so long for my package to get updated - maybe the original info was corrupt of wrong (for example containing the wrong references or the wrong service) and they resent it.
haha it was interesting on the phone with the Apple guy though... never the less, I am going to head out for the night.
Gentlemen, I will talk to you all soon. And we will certainly see if our packages get on that 7 AM(EST) from Guangzhou tomorrow morning

Goodnight, and happy tracking
