If people don't want another occult pack, then genies/djinn could be a part of another travel world/tomb raiding adventure type pack. Though I would love if we could build inside of genie lamps and bottles XP
I noticed that Spellcasters swiped some of Sims 3 Genie abilities (summoning food/Delicioso, cleaning Sims and things/Scruberoo and Ensorcel Sim/Minionize). Not to mention fairies stole the floating over walking. This makes me think that either they won't make a genie (if this is like the issue of gypsies being a stereotype that is offensive) or it is going to be like a temporary state or unique character like Bonehilda.
I still hope we get the occult, but it looks like it might be redone, or recycled abilities.
