To refute that, they would have not just to release numbers, but some kind of statistical model that explains how this can happen and how it is totally not their fault and what not. And... I don't think such a model exists. Maybe it could be created, if you send a few business analysists and mathematicians and psychologists on the job and let them research a few years or so. That would certainly be fascinating to do, but Wizards of the Cost is not a research facility, even if they have an R&D department.

And they still can't make any money with it. Oh, and it might give competitors insights into WotC business that they could use against them, too.
