I know there is We Rule coming soon after launch and SimCity... long after launch, but are there any other city builders coming to iPad? It seems the perfect platform for the genre. City-building games are a genre of strategy computer game where players act as the overall planner and leader of a city, looking down on it from above, and being responsible for its growth and management. Players choose building placement and city management features such as salaries and work priorities, and the city develops accordingly. My favourite city builder is Caesar III, where you rise the ranks of the roman empire and are tasked with managing various cities: It has more depth than any current city builders in the App Store and really lets you make your city your own.
We'll have a city builder released soon, Virtual City! Actually, the player has to manage a trucking company, but the game involves a lot of city building activities as well. You can check out the game play videos in this thread.
