Not exactly the way they work, though. They will build good to great systems, much better than "good enough", and leave lots of room for us to build on top of them if we choose. They will also build new content over time, I would guess official an unofficial, as well as tweak things that have minimal chance to break the ecosystem to improve overall game play. In other words, they will not likely ever completely abandon 7DTD.
Someone will likely build an overhaul mod making 7DTD into Sesame Street, for example. Today's horde brought to you by the number 7 and the letters F and U. Well, it could happen.
