I think they'll only ever come to Sims 4 if we get a Supernatural EP, as they didn't rally very many votes in the occult life-state polls the Gurus ran. Even Imaginary friends scored higher.
And it's clear occult are only added to packs when absolutely necessary for the theme, the fact they didn't even make it into Pets, means there's no way they'd get into a farming or dating EP. I also don't think werewolves are really 'magical', but more monstrous, so I don't see them in Realm of Magic.
I definitely want a Farming GP/EP, but if they pull a Strangerville 2.0, I feel that would become the focus of the pack to the detriment of the farming. Also, if there was a special extra feature added to farming, I'd want it to be horses.
