Don't worry, if they don't communicate it's because they don't have the time to because they are working hard on next updates, not only the mac port but you can check by looking at the most recent game files that they added a lot of space age buildings in january (they add content like every 2 weeks). Also the building berserker talked about that could build domovoi bricks is basically ready, so is the aircraft carrier.
But there isn't just that from what I saw, so if you don't want to get spoiled don't read further:
Whether or not it's in the location after gypsy tabor, there is an underwater world with oxygen left to manage, chinese buildings, "victorian" that are dark buildings and "bunker" walls.
