According to a story on GameSpy, a new patch is in development for SimCity Societies which will add content and additional features to the Tilted Mill Entertainment developed city simulator.
Expanding on the strategic mode introduced in a previous patch, the upcoming update will introduce new interface elements to help control more complex cities. The UI update will also include a building filter, and improves emergency services management.
When it comes to new content, the game will receive a new "Alien Invasion" disaster. Aliens will invade your town with their UFOs -- said to be similar to the ones that appeared in SimCity 2000 -- and blow up random buildings.
Lastly, the patch will include additional performance enhancements. Expect to see the update next week.
