As a helping artist for the main team, I'm afraid no, it's not planned. However as a modder (Make sure you check out Milenium AD, Rise of The East, and Aristeia, and any other mods that may come out, I must say it is possible that if we come with a perfectly designed faction devs might consider to add it in the game. HOWEVER, I am not part of the main team (Yet). And seeing how hard it is to balance the current factions I'm affraid it would be a terrible amount of work for little to know benefit if you take out the germans rocks argument. So it's a MAYBE there will be one, but NOT LIKELY in the main game.
