Forgive me if this has already been addressed. I haven't seen anything discuss it yet. 
I noticed the CV screen shots to date don't show any cottages/villages/towns surrounding the cities, but do have farms and pastures.
I don't like cottages in CIV from an aesthetic point of view, but they were important to build for commerce, and I also liked the idea of certain worked tiles producing more resources after a certain amount of time. But both of these could be addressed in other ways, so I'm hoping that there is more to it than the screen shots just overlooking them for now.
