According to Heroic Corner, some details about two new factions, Academy and Sylvan, featuring developer comments about the evolution of town concepts, have been published in a popular Russian magazine Game Land. I will try to acquire a copy and post them.

It should be noted that nothing was said about the Dungeon town. It can be speculated that Ubisoft intended it to be revealed last, so it seems to support the theory that the revamped Dungeon, which features some kind of dark elves, is the promised brand new town.
