Ordering a 7 Plus 128GB black (Tmobile) from Apple gets you the device between 10/1 and 10/7 so its highly unlikely that all 9/9 pre-orders for the larger device and capacities have automatically been delayed till November. If apple/tmobile were to do this, there are likely to be massive cancelations with folks moving on to perhaps the cheaper iPhone 7.
Other carriers have been shipping these colors and capacities and many folks have already received them so its also highly unlikely that Tmobile would somehow be the sole provider that has pretty much all of its pre-orders delayed by a couple of months.
I ordered the iPhone 7 plus 128gb black from T-Mobile and the estimated ship date is November 1, 2016 - November 30, 2016.
