There has been so many "hints" recently in game with new objects, careers and so on.. that something education related is probably coming soon, be it university or even better more than just that. Also vehicles, sports related stuff has been more there recently. I think that firefighters, burglars and police NPCs are coming somewhat soon too.
I still have some things that haven't even seen/read yet since I've spent most of the time building and CAS, and many of those "hints" are/happen in play mode too. Also I still have StangerVille, Laundry Day and My First Pet Stuff missing from my game since they haven't made bundle of them, and seems like they don't do those kind of bundles anymore.. sadly. But I have seen stuff from those packs too already, because I like to know pretty lot about the packs before I decide if I would buy them or not. (Not too much though, so there would be some surprises too)
If you ever read things that are written in game, you would have noticed those "hints". Also themes in things have those. I think that English version might have them even more clearly/obviously, since with translations they might not be as much clear/obvious.. or could be otherwise too.
And of course I know that there has been things in game from the start related to anything, because how can there be not? You can just take anything as a hint if you want so. I just personally like to think that they do hint some things in the game and have always done so, even if this wasn't the case. But yeah, it's always that when something is coming soon there is more stuff related to it before it comes and that just what I've noticed in all these years that I have played these games.
I hope this education/university pack is really coming soon! I've been wanting to have some more education options, and related careers, for my sims. I like that there is something like that now in freelance career, that art class thing for example (I don't know how it is in English version).
