Modiphius Games, who also owns the roleplaying game license for Conan, just announced that they are indeed the ones who has bought the John Carter license! Not only will they release the roleplaying game for Christmas of 2015 (with the same gaming system as Conan, the 2D20), but also in 2016 a miniatures game and a boardgame!
