It is hard to say. I am a little pessimistic on this front, so maybe until the game bursts at the seams and collapses.
It isn't that I want 4 to end, so much as a lot of it feels built on pillars of sand. Sims games in general experience bloat and destabilization after so long, but none have had such a drawn out lifespan as 4. Even with cutting content into perfectly square, small pieces eventually the minimum specs of 2014 just will not be true. In the meantime, people with hardware that could handle more languish.
There is definitely still more stuff I want, but I do wish there were more ways to tailor the game to your own hardware rather than being stuck to a stock standard. It would theoretically be more liberating, too, like cutting off the tail of the legacy edition.
