According to said page, there are the following as-yet unheard of features:
Establish embassies at foreign courts for closer ties (or clandestine operations
•New Wonders: There will be 9 new Wonders with all new effects including Neuschwanstein, the Great Mosque of Djenne, the Terracotta Army, the Great Firewall, and the Hubble Space Telescope.
Not sure sure about the Great Firewall myself, sounds like it'd be controversial. Nonetheless, a good espionage wonder per chance?
