I think, city states will probably be famous cities per se or cities that represent/come from small states. But I also think they will stay away a bit from (too many?) cities that will belong to an expansion civ. Meaning cities like Pergamon, Hattusha (if no hittites), Samarkand, Ashur, Milet, Pella (or other that may be Greek), Santiago, Prague, Krakow, Belgrade, Zurich, Bruxelles, Dublin, Toronto, Montreal, Buenos Aires, Vienna, Melbourne, you get the idea, like the Barbarians, and a bit temporary based ;-)
