I think (and hope) they will go with the ''stereotypical'' witches (pointy hats etc) and the more 'normal/modern' witches like charmed.
I think if they take the vampire system and modify that one, where it let's you pick good/bad/neutral spells will really make the gameplay nice and diverse.
Being able to kinda mix and match the type of witch you want to become will be great. I really liked the good/bad witches thing in Sims 2, so I hope they will bring such thing back.
Evil Sims being able to make Sims sick, put them into negative emotions, curse them etc.
Good Sims being able to make Sims better, make Sims happy, Give Sims skillboost buffs etc.
Neutral Spells like weeding every plant on the lot, harvesting everything on the lot, cleaning the house instantly, fixing broken objects etc.
Witches are the only occult I really still want, so if it ends up like this, I think it will be fun.
