This should be ok. They just don't show it as shipping yet since they are still processing orders. I called and asked about it and the Apple rep said that the orders promised on the March 16th date will still go ahead.
it should be ok - i ordered 2 iPads on one order as soon as they were announced. 1 is showing as Shipped and I've received a tracking number for it, and the other one is showing as preparing for shipment.
I ordered the new iPad, 4g, 64gb over the web on 3/7/12, with expected delivery on 3/16.Last night I ordered another one, this time for my wife.
Today, when checking order status****WHAM*** Cancelled without explanation.After several calls to Apple, I had to accept a 24 hour turnaround time at getting to the bottom of this.After this, I googled "new iPad cancelled orders" and found out others suffered the same fate.I can't re-order, since my card was still charged for both.
