This is also why Motorola has cut production of it's wifi version of the Xoom, and nearly every company is cutting production of their tablets. They simply don't sell.
What we do know, and reported from Apple, is that 9+ million iPads made it into customer hands for the quarter. What we don't know are return rates for those iPads.
