I'm not trying to quash your hopes, but why would you find the fact that not all the orders have ticked over to the delivery date yet to be more concrete that Apple's official press release?
Street date is street date, I think.
Agreed. They may "ship" earlier but Apple will definitely hold up the shipments like the WiFi release so they arrive on Friday.
Never the less they will probably prepare the shipments in the order they were received, and we will see them ship in a likely similar way to before.
