Same position as you. I don't think I had reservations in history on previous launch events, I kept the emails just in case.
Doesn't show up in "my reservations", just use the email, suggest taking a print out if you can too but its not necessary
Nah just an email, when you go on the day they just ask for your name and they have a list on an iPad and sign you off and reconfirm your order.
Thanks guys. I did call the Apple Store and check with them and the guy said they can't see reservations on their system yet, but an email means it's guaranteed.

Now I have to decide between Gold and Grey. Gold with a Saddle Brown leather case sounds like a nice change in honesty...
