Stay positive my friends! I'm going to be that annoyingly optimistic person who says "it'll all work out in the end" until you feel like punching me in the face.
Do not fret. I've said this like 4 times already, but AT&T is being very conservative with the dates as CYA right now. I wish I could give you more details, but I'd more than likely get in lots of trouble regarding my employer. But take it from someone very close to the company in discussion. The chances of you getting your 6s Plus on launch day (unless you ordered later in the week or Rose Gold) are very, very high even if the current shipping estimates don't reflect as such.
