Is this promise about future Sims 4 content true?

I didn't even play sims 4 for the first two years because it was boring to me. That is 2 years they didn't get any money from me. I'm sure I wasn't alone in not switching right away. It would make sense to continue to produce sims 4 content in people continue to buy it. Hopefully they continue to do so. As far as buggy, the game still works for me. Every now in then I may get a glitch but it's typically fixable in game and I continue playing without loss. Nothing like the sims 3 where the whole game would just randomly crash.
