FTA: Analysts had predicted between 5 and 8 million launch weekend sales across both devices

That is a link to another earlier article on Apple Insider discussing such predictions:

"In fact, Kuo said in a note to investors on Wednesday that Apple will likely ship 6 to 8 million new iPhones over the devices' first weekend of sales. By comparison, Apple racked up 5 million sales when the iPhone 5 debuted last year. Earlier in the day, Piper Jaffray analyst Gene Munster forecast 5 to 6 million unit sales, a more conservative number based on the prior model's in-store launch sales."

Notice that the higher numbers are shipped, not sold.

The iPhone 5S seems to be selling briskly, but how many 5c are still in the channel after 3 days?
