For those still waiting for movement on their orders, here's my status update -
Ordered a 42mm SS with Milanese band on 4/10, received email confirmation at 10 minutes after pre-orders went live, delivery window of 4/24 - 5/8. Had seen absolutely no movement until FINALLY, this evening my credit card has a pending charge and my order is now Preparing to Ship. So much for the under promise and over deliver line, but with any luck I'll have my watch by Wednesday.
Probably completely unrelated, but I did have a chat with an Apple rep online this morning about my order. Didn't give me much info other than there were no "red flag" issues on my order and that until my shipping window passed there was nothing additional they could do for me.

R - If you ordered a 42mm SS watch, it is coming, but probably not until the later part of your shipping window.
