I honestly find the whole "Pathfinder is outselling 4e" to be more thna a little flawed. Besides the good points about DDi being ignored in the PF vs. 4E sales debate, the claim that Pathfinder is selling better and therefore is better also ignores that 4E books are in a deliberate tail-spin as WotC has basically washed their hands of the edition. We're getting what looks to be the last 4E books in next month, and then that's it. Nothing but system-neutral FR fluff-books until next year, and probably ever. This is on top of following a year where the production numbering and quality has gone down. Add to all of that that people are being told their investment in 4e was going to be invalidated in a year or so due to the release of Next, and I'd be more shocked if 4e sales hadn't bombed. You're comparing a game line that's having its life support pulled to a game line in the middle of its prime with full support from its parent company. Trying to prove the Pathfinder is somehow better than 4E by pointing to the dead-tree sales at the terminal end of one edition while the other is in full swing is like saying a ten year old has always been a superior athlete to a ten time gold medalist dying of stomach cancer because he can walk faster at this moment. I would have to wonder how much feather preening would die if people stopped comparing PF core-rulebook sales to unpopular 4E splats, and instead compared the two game lines when each was at its peak, and accounting for the money making monster that was DDi.
Finally, as was point out not a few pages ago, the reason 4E is being pulled isn't because Pathfinder is "beating" it, but because Hasbro set an absurd standard for DnD to live up to, and many people have rightly pointed out that its still wildly unlikely that even if we all started playing the same "edition" that DnD could make it. 50 Million a year is a lot of money to make for a Niche within a Niche within a Niche.
There is a lot of dumb B.S. going on in the game market, but Pathfinder gets too much credit for it.
