I'm a little lost on how Mansions = Generations, other than lots of rooms? I guess.
But I tend to build Victorian manor houses, complete with former staff areas "downstairs" Granted, I'm not a gamechanger. But I think that's a stretch.
I've looked at what was in TS3 Generations, and I think it's far more likely we're getting a School pack to expand upon Child and Teen lifestages which will cover the bulk of what was in Generations that we don't have so far. (There are still adult and elder elements missing, those might come in stuff packs or a future Game pack.)
But then, other than the financial benefit of having it all in one pack, I don't get why people want Generations to be specifically "Generations for Sims 3 exported exactly for Sims 4" 1) there are several systems that TS3 Generations added for that game that are already in TS4 (dating, I believe being one example). 2) I think there's more potential gameplay development if they split it between packs (See Vampires)
