As you have probably heard, Hasbro via Kre-o is releasing Dungeons and Dragons block and minifigure sets. Shown here are some of the minifigs. It appears that these products will be a little like Crossbows and Catapults. It has cards and uses working catapults and ballistae. This link has more pictures of what will come in the battle box.
As far as I can tell, these do not come out until January of 2014 which seems like a big missed opportunity for holiday sales.
