Ordered XSX on launch day, console warranty active since launch day, shipping estimated to...

It depends on when you ordered it and where you ordered it. If you preordered it for launch you should get it the day of release. If you preordered from Microsoft fter the launch consoles sold out, it'll ship November 30. Your order should have an estimated
date listed on it.

I pre-ordered my Day One edition from Amazon on June 14th and because I opted fro FREE shipping, my estimated delivery is between December 2-3. I almost always receive my items from Amazon earlier than their estimates but nonetheless, I will still have to
wait a few days after launch for my Xbox One.

I pre-ordered both consoles through Amazon.

If you order through Amazon, they have launch day bundles for the PS4 that are still available for pre-order. Since Sony has not given an official release date, my shipping date is 31DEC. However, the launch day edition (no bundle) is unavailable for pre-order.
If you pre-order the standard edition (not launch edition), you MIGHT get an email later on that says Amazon upgraded your standard edition to launch day edition, guaranteeing you will receive yours on that day. This also applies to the Xbox One, which is
what happened to me. I pre-ordered Xbox One on 15JUN, then I received an email six days laters that said Amazon upgraded my pre-order to launch day. Keep in mind, there is only one bundle for the Xbox One, so I would do it fast.

This launch day I'll be crying silently to myself patiently waiting until around the end of December for my Xbox One to be shipped to me since I didn't pre-order anywhere near soon enough to get it on day one

Well, it supposed to be delivered on launch day. Back when i pre-ordered the Xbox One, it came on launch day and I ordered from MS then as well. I still have not been charged yet though, unless they are shipping to the depots over the weekend.
