I've been more involved in the Space Gray/EOD threads because I've been trying to find out what will happen with my BF's watch, but here's some shipping info for MY watch (38mm white sport):
--I got the actual shipment email overnight with a tracking #
--I have the watch on my support page now on Apple
--The shipping window still says 04/24-05/08 on my account page, but the *Apple Store app sent me an iOS notification that I'll receive the watch by tomorrow*. I have no other proof of a specific date besides that notification center message.
--UPS just says: Harrisburg, PA, United States 04/23/2015 1:50 A.M. Package is in transit to a UPS facility. It doesn't tell me an estimated delivery date.
