Order confirmation was sent to me at 3:08am EST, so I too hope I am in the first batch!
Last week was easy; I checked my order status maybe once a day, but now I am just being an obsessive checker!
My deliveries app ALSO says May 8th.... 18 days from now! That seems crazy to think about, but I too think that is just because it is the latest date. If I was running apple, I wouldn't want to get thousands of customers enraged if I said delivery date of April 24th but it ended up being the 25th or even the 8th of May. They seem to be playing this awfully safe. I don't blame them!
In my own personal experience, apple tends to UNDER promise and OVER deliver with these delivery times. I remember I ordered my gold 6+ 125GB in a Verizon store the morning of the pre-order, and they said SIX WEEKS until delivery. Well, I was so surprised when less than 2 weeks later I received my delivery. Pretty awesome, although I obviously cannot promise this is what apple will be doing with the watch.
I'll be refreshing hourly and updating the thread if I get a ship notice!
