Given that I still play 2 and 3 in addition to 4 on the desktop and Freetime and the mobile version on my phone (when I actually have time to play--unfortunately, real life has a habit of limiting that), unless something drastic happens or unless I lack any free time to play anything at all, I don't see myself not still playing Sims in some incarnation in the future. I'd likely even still play Sims 1 if it was possible to play it on my current desktop or made compatible to play it on "newer" hardware and operating systems.
