What's The New Sims 4 Experience?

The 'new experience' is another stuff pack. They said the same thing when they released Fitness. But a new direction (soon) is being able to sync your mobile game with the PC game to level up your Sims etc. That was planned in the beginning and I don't think that idea has been dropped just prolonged until console and mobile were released. We'll see if I'm right eventually. ETA: To back up my speculation and that is all it is, you already see you get stuff in one game if you get the other. There is going to be a whole lot more stuff like that and that checking up on your Sim's progress is not thrown in the trash yet.
