I definitely want some occult careers, but if we are talking occult lifestates, then I want werewolves. It always feels a little odd to me to have vampires and not werewolves in my game. Be it in 2 or 3 and now 4 when I had to wait for them to be added. I like the set them juxtaposed, a foil if you will, to my vampires.
Plus, while I was disappointed with spellcasters, I am hoping they will double down on what made vampires great in 4: the gameplay. The skill and weakness tree is a huge element of that, but also things like the sparring interaction, showing off powers, the new bat woohoo, coffins, etc. Things that were undeniably vampire that were not set dressing. I would happily welcome something following nearly the exact same formula. Small world based around the life state, skill tree, related BB and CAS, etc.
This all being said, I would love to see so much more supernatural stuff added. This isn't the beginning when I could hardly pick a career for some of my Sims because there were too few "plain" options. Now I need much more variety.
