The EA newsletter the SimInsider which covers all games in the Sim genre briefly mentions SimCity Societies in its latest edition with a short article that covers the most important changes in the game. In addition the official site has been updated with a basic about page with some of the features listed; including societal energies, the ability to share you cities online and a building block tool kit. The latter which should not be confused with a building architect tool. We have yet to hear anything officially mentioned about such a thing exisiting.
SimCity DS is also covered. Check out the homepage if you haven’t already.
