Huh? How is that 2-3 weeks? If you get it on the 10th, that's exactly 1 week from launch. If you get it on the 17th, that's exactly 2 weeks from launch....hence 1-2 weeks. Not sure how you're coming to the conclusion that 10-17 is 2-3 weeks. Only way I see it as 2-3 weeks, if you mean from today.....but I always took the estimates as based off of release day. Again, in which case, we're in the 1-2 week category.
Apple order page says it ships in 1-2 weeks. From the time of order.
Otherwise it would/should say it ships in 2-3 weeks, and that would actually be the 11/10-11/17 time frame that it lists as well. Whenever you order from Apple the ship date is from time of order, which is why that data was confusing.
