Pony settlements besides Maretime Bay, Zephyr Heights, and Bridlewood: Are there any?

[heavens-champion 1,879]

You, I've been thinking, and it has occurred to me that the only towns in Generation 5 so far are Maretime Bay, Zephyr Heights, and Bridlewood. Will we see other cities in Generation 5, or did every pony from each tribe decide to live in their own city?

given that maretime bay is a city, there must be many smaller settlements near it, and probably a whole network of cities to support it.

given the Zephyr heights must have vast supply chains and manufacturing for all their fancy gadgets, there must also be large populations of ponies to support it

only Bridlewood makes me wonder if there's no other unicorn settlements.
