... Well, there goes another thing with a Mario crossover.. What's next??http://www.explosion.com/82102/puzzle-dragons-super-mario-bros-edition-announced-launching-year-3ds/
Anyways I know several people who play Puzzle and Dragons on here and thought some might find this interesting. The 3Ds in japan earlier last year had P&D released onto it, though never making it west that I know of.
Most likely since the new one will be a "Mario" cross over we'll see it.
