I haven't heard anything at all about sims from past games making their Sims 3 debut in Seasons. I don't mean distant second-cousin-type sims with the same last name, I mean sims we know and love.
I'm going to say Cyd Roseland. I always liked him, and even though he had the criminal want, I always turned him into a mild-mannered school teacher looking for love. With that idea of him in mind, the online dating and festivals seem really great to find Cyd the love he's been looking for.
Of course, I'd love to see the rest of my all-time favs, the Tricou family. Since they gave us only one member in SN, I don't see them bringing the rest of the family back, or Rainelle, for that matter.
Any past sims you'd like to see make a return in this EP?
Tell us about it!
Edit: I know there's no world with this ep - what I meant to say was the new store world that I heard is being timed to be released near Seasons - either shortly before or after. In my mind, I think of it as the Seasons world, and that's how I typed it, not thinking at all. Sorry!
