I am debating whether to early upgrade to 5S from 5. My concern is this: Everyone here seems to assume a larger iPhone (iPhone+) won't come out for another 12 months. However, iPad launch pattern suggests that you may want to launch screen size variation on an offset cycle to help keep your demand curve less lumpy. Having a sequence of phased launches helps bring people into the stores more often driving more revenue. Given this, it would be logical for Apple to launch a 4.7-5.7" iPhone in the February-April timeframe, and then launch the new 4" models next October. When I combine this with the press saying that Apple was testing large screens towards the end of the first quarter, and I'm left thinking the notion of a 12 month wait for a larger screen may not be right. Any thoughts?
