You ever track an iPhone launch shipment on UPS? For that matter, have you ever tracked an iPhone post-launch shipment? They come direct from China. The iPhones only ship a few days early because of capacity; there's much less demand for the TV, so they don't need to have UPS hold them.

You never know for sure what's going to come directly from China.
My 6s, ordered a few minutes after the pre-order began, originated in Ontario, CA as did my 5K iMac and Magic Trackpad. My previous iPhones have always shipped directly from China. You never know.
