There's no doubt there will be new villages. They haven't even said Hyrule will be in it, although I wouldn't doubt the land below the clouds filled with evil is pre-hyrule before it was ever created, as this is supposedly the first game in the timeline. The land above the clouds is bound to have new cities and towns, and very likely new races, like a cloud-based race (NOT the Oocoo. I sure hope those are TP only races, they better not come back) The land below the clouds, it's filled with evil monsters, I don't think there will be any new towns, although I could be wrong. I would imagine down there is just where the dungeons and the like are. There could be towns and villages. The villagers will probably be terrorized by monsters, but there could be.
