I think we'll be getting a romance system with something else, and probably soon.
By "with something else" I mean that the pack (probably) won't be just the new romance system + attendant build/buy and CAS. It may be as small as just a new destination world in a game pack, or it may be something more complicated like Hotels/Casinos (& Heists? I can only hope)
But this 100 Baes challenge, especially given that per her first episode it was designed with EA, is definitely giving me romance pack vibes.
(Just please not with Werewolves under some sort of "Animal Attraction" idea. I don't want the Normal players demanding the nerfing of my precious Werewolves.)
Then again, I've been sure we were getting a school based pack/update for about a year now, and that hasn't happened either.
