Oh man, if that is true, this place will be insane by Wednesday!!
This reminds me of when I commonly preorder video games from amazon. I have Amazon Prime and get guaranteed release date delivery. The most recent one was Killzone 2. I preordered about a month before the game came out. There were people freaking out because they preordered it like a year before it came out and it was 2 nights before it came out and it hadn't shipped whereas there were people who ordered only a week prior to the game being released and they had received tracking numbers via email. The boards over on amazon were hysteria with people cursing Amazon and the shipping providers.
Low and behold, release day came and everyone had their game safely in hand. Believe it or not....companies such as Apple and Amazon have been around and know what they're doing (most times) and shipping companies such as UPS know how to ship items. There are many factors that go into this such as proximity to the distribution center, travel time, etc. But if your order status says "Delivered by June 19th." Chances are, baring a giant catastrophe, you will receive your little plastic device. A week from now you will forget all about your worrying and just be enjoying your $200 piece of plastic.
