Hmmm - some quick researching seems to suggest that there would have been bison in ancient Mesopotamia and Anatolia, and both the Sumerians and Hittites considered 'bulls' to be culturally significant (they appear in many of their myths and legends), so it is possible that the new data could all relate to some WotAW-related thing. Then again, we have seen that screenshot of CotNW Deluxe, so Firaxis were definitely working on that at some point. It'd be strange for them to completely abandon it. I wish 2k would give us some new information. Preferably before Christmas. If both of the scenarios were remade with BNW mechanics and 2 new civs each I'd be very happy. Even if they aren't going to be ready for release before Christmas, I really hope we hear something about them. The complete silence is very frustrating.
