We haven't seen anything from Town recently. I wouldn't be surprised to see this at E3.
A bold prediction of mine:
Town will be free to play for Nintendo Switch Online users, with additional paid content for people (i.e. outfits, weapons, etc)
I really don't remember much about the game from it's initial reveal, other than it's a game based on a person you control and you build up a town and defend it from invaders. If it's as simple as that, it might just be free to play. Plus, if memory serves me, it's developed by Game Freak? It might be a good way for them to experiment with games outside of Pokemon.
