Springfield airport plus new area?

They've told us that technical limitations make it hard to add more land and still keep it compatible on older devices - i.e. people who have been playing for a while and haven't upgraded their device.

So while I would like to see more actual land for a bigger town, having a separate map/area is a great idea to me to allow more. But to just have more Springfield? Naw, it would have to be something really good. Airport? Interesting, but not enough for a whole area.
