Where did you get those numbers? As far as I can tell, more that one hundred cities have textured buildings in Google Earth (they were created by building maker https://www.google.com/intl/en_uk/earth/learn/3dbuildings.ht...) as well as in mobile maps (http://www.google.co.uk/mobile/maps/3d/ my city has 3d outlines and it's not even in the map). Apple maps too should have at least 40 cities in 3D.
