For all of you still holding out on hope...
I ordered on 9/9 and got through at 3:30 AM CST.
Today at about 7PM CST, I saw on my UPS MyChoice a new shipment, then about 30 minutes later Sprint sent an email saying my device shipped (this was weird because they did not send an email last year for the 6S).
I did not choose or pay for Express Shipping but still got UPS Next Day Air Saver with a scheduled delivery of Tuesday!
My order number was oy-shso-803452XXXX
P.S. I was told MANY lies, some by people on this forum, some by chat reps, some by CEOs of Sprint, etc.
I was told I wouldn't get my phone till Oct 7th, I was told I would get it Oct 16th, I was even told I would get it Launch Day. All of which were lies.
Basically what I'm trying to say is hold onto hope because the week/weekend is still young and you never know when you could get the email. BUT! Take what other people say with a grain of salt because you'll either get excessively ANGRY or desperately HOPEFUL (which inevitably leads to disappointment)...
Good luck to everyone who's waiting and congrats to everyone who has their shining new devices on the way!!
