Zynga teases new CityVille Factories, Active Buildings and more

In a recent community outreach post on the CityVille forums, Zynga community manager Mayor Max hinted at several features that are en route to the city-builder. Apparently Zynga is quite pleased with its work on the Visitor's Center and claims that more "Active Buildings" are coming to CityVille. Our guess is that we'll be seeing more buildings that more functions than providing coins and XP. Again, the company teases Factories and says they will be "zero-emission" and produce ... something.
