Bloomberg, via a state-owned Chinese business newspaper, is saying the iPhone 6 won't be going on sale in China this year. Supposedly Apple has been unable to reach agreement with the Ministry of Industry and Information Technology.http://www.bloomberg.com/news/2014-09-16/china-mobile-expands-4g-rollout-amid-phone-subsidy-cuts.html
As in past years employees can reserve one iPhone for themselves, but this year only the iPhone 6 and not the 6+. That serves as further evidence that the 6+ is in short supply. FWIW Kuo had come to the same conclusion well before the actual launch IIRC, guessing it might be November before it became widely available.
