According to ICV2’s Internal Correspondence, D&D has now slipped to fourth place in overall sales in the retail sphere, behind Pathfinder, Star Wars, and now Fate.
This shouldn’t be surprising, and the Q2 numbers are likely to be just as dismal for D&D. With the imminent release of 5th edition, and no 5th edition material being generally available until July (other than a few pdf offerings that don’t register in the retail sales channel), customers are holding their collective breath for the new edition.
Look for D&D to vault back into first place come Q3. The interesting question will be how it fares once it gets over the initial bounce.
