With Wizards of the Coast releasing old school D&D supplements via PDF this week, I thought I would take a look at our D&D core rulebook sales for 2012. This is a bit different in that it includes the reprints of AD&D (1st edition those just joining us) and 3.5. Our sales numbers include just the PHB, along with any bundles we sold that included that book.
For Pathfinder, the data includes the core rulebook and the starter box, two gateways to entry that may overlap. For D&D 4, it includes the Player's Handbook, the Heroes of X books, and the Red Box starter set, again with some potential overlap.
My general feelings are that there is more interest in AD&D than 3.5, with 3.5 close enough to Pathfinder to migrate those players down the road to the New Thing. Thus, we have Unearthed Arcana for AD&D getting a reprint soon and no word about 3.5 reprints, which I think, beyond the core books, aren't necessary. So please, go right ahead with AD&D reprints, but I may have to pass on 3.5.
