What else will we get in Sims 4?

Sims 4 is approaching it's 4th year. Sims 2 and 3 were finishing up and getting ready for the next version at this stage of the game.

So, what's left?

Is Sims 4 going into a 5th year? Will we get any new versions of Seasons? Showtime? Supernatural?

Anything completely new, like Into the Future and Island Paradise? Maybe Into the Past?
