For what it's worth, I ordered the 128 silver iPhone 6+ on the VZ site at "about" 3:55am EST. Took a screen shot of my order confirmation page reflecting the 9/19 received by date. Received my confirmation email about 90 minutes later with order and shipping dates both displaying 9/12 dates. Called customer svc yesterday, was told all is well for the 19th.
See this thread today, check my order status, says ship by 10/14.
Just got off the phone with customer svc again. Rep told me "looks like you just got it in on time, you should be good to go for the 19th". Explained all that I've seen and received so far, plus the fact that my card hasn't been charged yet. He told me the card will be charged Tuesday or Wednesday next week. I believe he knew of what he was speaking, because he pulled up my order and confirmed the numbers with me, without me giving them to him first. Plus, since I added a line when I pre-ordered, they actually assigned a phone number; which I was told doesn't necessarily occur until they are ready to ship.
Take it for what you will, the conversation occurred about 20 minutes ago.
