If you haven't seen movement yet, you're not getting it on the 3rd.
But, there are 14 days between the 3rd and 17th that Apple is surely going to be shipping and delivering. Keep calm until the 3rd passes, I have a feeling we'll be moving really quickly after that.
I doubt we’ll see the date change at this point assuming nobody else is bumped to the 3rd. If anything, you’ll just see your status change to preparing to ship.
That’s how it happened with my Apple Watch last year. I had a 3-4 week delivery, and about 1 1/2 weeks in, my status changed on my order with the estimated delivery date never changing.
