I've been reading this thread for weeks and after being sucked in to the paranoia, I thought I'd share with you my conversation with Apple in regards to delivery on launch day. Here it is....
I'm afraid that this is no reassurance to those of us who ordered early (1:08 am on the 10th in my case) and have an email confirmation of order stating delivery by the 28th, but order status which says ships by the 28th.
