I decided to go ahead and upgrade today. I got to my local store around 11:25, they open at 12. The line was probably about 75 people long. While waiting in line is used the Apple Store App to order a 64gb 6 in white for in store pickup. I went home to eat lunch and watch football. Around 1:00 I got the email that it was ready to pick up. There was no line for pick up, but still a line of about thirty walk in customers. After I checked out I saw a guy who was about 20 ahead of me in the morning line just getting to talk to some one. TL, DR: order online for store pickup instead of waiting in line.
