I have to admit that because of that GW article about Kislev i am thinking Kislev is a really strong candidate to be in the game 3. But, as we all know the most sure factions of the game will be Chaos why not do something crazy? Really crazy like.. adding the Realm of chaos? Think about it. Another theater of War like in the Empire total war. Or Mortal Empires map extends instead of much to the east but more to the north?
