EA has confirmed a February 2013 release window for SimCity.
The publisher also announced SimCity Social, a new Facebook entry in the series made by Maxis and Playfish that's expected to be released later this year.
Official descriptions of each game and new E3 trailers follow:
The defining city simulation is back! Create the city you desire and make the choices that shape your city and power the Sims within it. Every decision, big or small, has real consequences. Invest in heavy industry and your economy will soar-but at the expense of your Sims' health as pollution spreads. Implement green technology and improve your Sims' lives while risking higher taxes and unemployment. Team up with your friends to solve global challenges: launch a space shuttle, reduce carbon emissions, or build magnificent wonders. Compete on global and regional leaderboards to be the richest, the dirtiest, the happiest or the best place to visit!
In SimCity Social, there are no set linear paths to follow; cities evolve as a direct result of player-driven choice allowing for more creative freedom. As mayor, players will deal with unforeseen issues like fires, crime and pollution, and will make crucial decisions that will help them discover how their cities take shape. Social interactions in SimCity Social go far beyond just visiting friends' cities or using them as resources to complete tasks. Players can choose to build friendly relationships with other cities or form an intense rivalry through a dynamic and ever-evolving friend and foe system. With multiple options for city growth, unexpected gameplay events that shape the destiny of the city, and city-to-city relationships, players will see recognizable changes that bring forth aesthetic and gameplay alterations based on the decisions made in the game - for better or for worse.
