Last year when I got a Surface (US) it was shipped overnight. I got a tracking number one day it arrived the next (Launch day). Hoping you all get the same. however, to pull that off it had to be prearranged and the carrier had them staged at final destinations so they could all go out for delivery on launch day. That might be why you get the 3-5 day story from underlings that don't know the whole plan. It's also not likely anything anyone wants to advertise... that there is a pile of new tablets at every shipper location or wherever they are being held lest someone gets some spoiler ideas.
I didn't pre order my SP3, just waited until after launch...
