-Stuff about PF fans in store behavior-
This reminds me of a time I was gaming in-store(a situation that never seems to really go well for me). We had just set down to start Encounters, when a young lad came up(probably19-20yrs old). He looked at our various materials, and we told him we were about to start Encounters and asked if he wanted in. He rolled his eyes dramatically and said something along the lines of "Oh, you're playing 4e. It's a shame you're not playing Pathfinder, it's just so much better."
It didn't really amount to anything after that. We all looked at each other, as if to verify that this had indeed happened, and the guy got bored and went off.
Lisa got her data from distributors and my guess is they have pretty solid data on their own product sales
Unless WotC is doing better in terms of direct market. When I was co-owner of Golden City Comics, WotC offered better terms than the distributor we used in Canada for D&D products.
Actually, the problem Hasbro has with Canadian distribution through Diamond Comics Distributors might be a major effect. Since Diamond cannot ship WotC products to Canada, and since other distributors are more expensive, the Canadian side of D&D's market share may be far more direct-from-the-source than through distribution.
That Lisa could be wrong (and I am also not saying that she is) is something that we should keep in mind.
