Analysts and pundits who worried that demand for a large-screen iPhone may have been sated with the release last year of the iPhone 6 and 6 Plus would seem to have no foundation for their concern. While no concrete numbers on pre-orders are out yet, the new Rose Gold anodized aluminum color option for the iPhone 6s and 6s Plus has slipped to four to six weeks shipping time after the first day of sales, while Hong Kong completely sold out of new iPhone pre-orders on the first day.
