No. They make enough money with this iteration if we have to believe them, so why would they even bother giving us quality content and fix the game? People buy it anyway, so why would they care?
There isn't a simple fix for this game a bug patch can resolve. The core of this game is fundamentally broken from the beginning. So, in order to fix the game, they basically have to redo the whole core, which they will not do in a million years. That's what you get for pushing it into 'Online only' and realizing halfway development that it isn't going to work.
I cannot wait to find out what they will axe out as an experiment in The Sims 5. (Because you know it; less work = more profit. (At least it seems like it!).
