Although I would love a University pack, I am worried on how exactly they will knock it out. With the Sims 4 you can't escape aging, not even on vacations. For a University experience to have any impact it would have to take at least 4 sim days PER SEMESTER, which... all of a sudden the entire life stage would be eaten up by it.
Of course, adding a whole new lifestate just for the university might not be out of the question; in a different way they were able to add a new life state for Toddlers.
Also, part of the fun of Sims 2 University (and sims 3... ? I'm blanking out) was choosing your campus. I mean, it would be fine to only have 1 new world for it, but I would love at least 2 and oh god a Online Courses option! That would be kick butt to be able to sign up for online courses while working a job and simming in the normal state of things. That would be fun to see, and something new and different from what we've seen before.
