Should future Occults be in dedicated Game Packs (like Vampires)?

I really want witches, and the more I read of people wanting other occults the higher up my list I want some of them to be. Fairies and werewolves definitely. Zombies - no. Thank you. So perhaps a really wonderful magical EP with strong supernaturals, the table for their strengths and weaknesses has already been made with Vampires and reused in GF, we shouldn't have to keep paying for new versions of it, not at full price.
