Not really a surprise ; heck Penthouse just went Bankrupt and they had a much larger and more aroused market.
If you throw together a list of the Top companies in a given field, they usually do not have a Magazine selling along with it. The top Mags in a field are published by something else. Example: GM/Toyota/Ford vs. Consumer Reports or Motor Trend.
I'd bet though, that wotc isn't going to hand Dr/DuMag back to Paizo.
I wonder if CosPlay is gonna be a big enough The New Thing or trend, that it could be integrated into a "D&D and" magazine.
