I don't think so, I think Late november or December. They wouldn't want to miss out on bumper christmas sales.
If it went on sale in early December, that would leave a three month gap (Greater gap than between iPad announcement and iPad going on sale) and therefore plenty of time for it to go into production and get FCC approval.
I think the reverse is true. Introducing all their best stuff before the holidays is hurting sales because few people have the funds to buy an iPhone, an iPad and iWatch AND still have money left over to buy presents.
If they space it out, customers won't have to sacrifice one to get another and the likelihood that they'll buy all 3 increases. Also, they dilute their marketing... iPad will get drowned out by the iPhone noise and some may wait to upgrade their iPhone to get the iWatch.
There are other benefits to spacing out their launches including increased foot and online traffic and giving their competitors less breathing room.
Steve Jobs understood this but Tim Cook clearly doesn't and I really don't get this asinine strategy of staying quiet for 9 months and cramming everything into one season.
