More famous characters will no doubt appear as purchasable entities, but the connection to the Tolkein mythos is sufficiently skin-deep that I do not anticipate coveting them.
That said, it is challenging to try and figure out what will happen to the Wii U once the Playstation 4 and Durango are released, and up and comers like the Oculus Rift start to inch closer to a purchasable product.
