The level of evidence you're demanding is simply unrealistic. Did Harry Truman really win versus Dewey? At least there we have one piece of data that claims otherwise.
No, its not. I'm not demanding any evidence at all. I know that "you" (those proudly claiming Pathfinder has seriously eclipsed D&D in sales) simply don't have the evidence necessary to support the conclusion, nobody does. I'm content with not actually knowing which game is currently outselling the other, it has no impact on how I approach the hobby.
That's a bad question, actually, because it fails to specify anything in a meaningful way.
I agree it's not a great question, because, even in overall sales I don't really care who's on top. I don't think it has relevance to the health of either game system, either company, or the industry as a whole. But it's a much better question than the one being bandied about in this thread.
Overall sales is overall sales. Which company is bringing in more money with their flagship RPG game. Simple to understand and simple to measure . . . except that we don't have the data to answer it. Doesn't make the question bad, just makes it unanswerable.
