Well that’s an educated guess, no hard evidence on that one, but If you read my take on a single player game about conan:
You’ll see that it is in fact the natural next step for funcome, If they do another multiplayer they’ll just hurt Exile numbers and step in their own foot. reconstructing the Exile engine (which is kind of an open world in itself) It’s the smart thing to do. Specially since the success of the Witcher Franchice has already proven the business oportunity that is hidden behind a single player game with household name like Geralt of Rivea or in this case Conan of Cimmeria.
But it is pure speculation at this point.
