would guess your time-table is about right. These journalists will make assumptions to brighten their story. Might well take months for Foxconn to train 18,000 farmhands to produce an iPhone 5.
I don't know if Iphone 5 will be launch in June or Sept. But Sept/oct are going to be one heck of busy months if they don't launch Iphone in June. Given the rumor of more sub 200 Android tablet, it will be crazy for Apple not to do an Ipad mini now. They will have the Iphone 5 in Sept, Ipad mini in Sept/oct and Itv on Oct.. The advantage of launching Iphone in June is that they can launch Iphone 5 in China in 4Q and suck all the oxygen out of Window 8 phone once they established the momentum of Iphone 5..
