Exactly what happened. Got a notification a couple of hours ago that shipping had moved to the 19th. And I don’t have to go the mall. Woot!You may be fine. I ordered an Air as soon as I could, saw I could pick it up at an Apple store 90 miles away on the 19th or have it delivered free to my home on the 25th. Went for home delivery, four hours later Apple emailed an update promising delivery next Friday the 19th so it worked out great.
