Does anyone have hard numbers on how D&D, specifically, is doing?
To answer this question, no one does. Well, except the WotC people, probably.
Hasbro doesn't list segments in that
much detail, though net revenue in "Games and Puzzles" is up 7% year-over-year.
Though, Transformers is their biggest line. The only mentions I can find from their 2009 annual report:
"The increase in gross profit in dollars was more than offset by increased product development and sales and marketing expenses related to investments the Company made in both core brands and its digitial initiative related to its Wizards of the Coast subsidiary..."
(bad)
"The Company expects amortization expense to decrease in 2010 primarily as a result of the property rights related to Wizards of the Coast becoming fully amortized in the fourth quarter of 2009."
(good)
"In 2007 the Company reacquired the remaining digital gaming rights for its owned or controlled properties held by Infogrames Entertainment SA (Infogrames), with the except of rights to DUNGEON & DRAGONS, for an acquisition price of $19,000..."
(neutral)
So, really, this is a small amount of information regarding the health of D&D, though the D&D digital initiative probably didn't help.
