Porting over an entire game to a new engine is extremely complex and time consuming work. Hell, look at the trouble they're having even optimizing Crystal Tools for this PC, imagine porting all those assets to a new engine. If it had occurred to them that crystal tools might not be the best PC engine a few years ago, they might have programmed this new one with portability in mind, but somehow I doubt that. I think the best we can hope for is some kind of (well programmed!) DirectX 11 inplementation for CT sometime in the future. They did say a while ago that the head of the new engine's dev team was helping them optimize CT, so maybe we'll see some fruits of that labor.
