I ordered on June 3rd and inquired about a tracking number for my shipment. This was the response:
Thank you for contacting My Sony Online Support.
That unit is on backorder due to high demand. We will be recieving a large shipment on the 16th and will be able to promptly ship that item out to you then.
I received my shipping notice last night as well. Glad to see that Sony is making good on this deal. Perhaps, I will browse there site more often in the future.
