iPhone 6s preorders leaning heavily toward rose gold

Pre-orders for the new iPhone 6s and iPhone 6s Plus due out tomorrow are showing a surprising trend -- the new rose gold color has been the most popular finish for preorders.

The news came via AppleInsider, which received an investor note issued by analyst Ming-Chi Kuo of KGI Securities. Kuo received information from supply chain sources to said that the rose gold iPhone 6s series is making up between 30 and 40 percent of preorders. 

Foxconn Precision will benefit greatly from that color choice, as it is the only casing supplier for the iPhone 6s that has the capability to produce that version in mass quantities. 

Kuo also expects Apple to sell anywhere from 10 to 13 million of the new phones, with the 12 to 13 million range in line with the high expectations of Wall Street analysts who keep an eye on all things Apple. Kuo believes the number will be under 12 million units, possibly due to the supply chain still ramping up production.

According to Kuo, the Taptic Engine in the iPhone 6s, along with the special backlight module and popular rose gold casing, are all causing production bottlenecks. 

We'll most likely hear actual numbers for opening weekend sales on Monday, September 28.
