I believe this thread was meant for people who ordered through AT&T's website, not through apple.com or the Apple Store app. Virtually everyone who ordered a 6s Plus through Apple within the first few hours received a 9/25 delivery date. If you are one of those people, your posts in this thread are irrelevant.
Myself: I ordered via AT&T Premier on 9/12 at 12:18am PDT and received a shipping estimate of 10/16 to 10/23.
