Today's announcement is just to say that there's been a good deal of nittty-gritty optimization to the game loop and state-checking - which, in all likelihood, no one would ever notice if I didn't make this announcement. It's just the right thing to do, I guess.
The City-themed stage is forthcoming, now that I've worked out the scale and some other details that were holding me back.
Stay tuned - it is possible you'll see a sudden discount for the Summer Sale very soon ;)
