GOT IT.
"Your Apple iPhone 6 - 64GB Gold will arrive on September 19th."
I missed the expected delivery date in the ATT email, which didn't come in until after I had gone back to bed.
Then saw this morning that the apple.com store was finally up, and showed that I could have ordered there for delivery by the 19th.
Hopefully come in early enough on the 19th so I can activate and restore from backup before leaving town for the weekend.
