I tend to think they'll be just like FC rooms, but...
Part of me wants to believe that it wouldn't take THAT long to implement if it was just a copy/paste of existing content.
Also, if they mean for it to be a way to help the housing problem, they need to make apartments good enough for people to want to get those, and not the houses they'll release whenever they do so (which might be in another 1+ year...)
Fingers crossed.
