To our recollection, this actually hasn't happened in quite some time. To be exact, in 2008, when it was the original Kindle. And, even then, Amazon managed to make sure they told customers when the Kindle would be coming back around, or shipping to their doorsteps. Not this time. All Amazon says right now is that the Kindle is temporarily out of stock, and that purchasers will get an email when the eReader gets an estimated delivery date.
