@ronaldjo25, no one really knows. Many of us are just volunteers and don't work for EA, but even those who are employees of EA and answer questions here either don't know themselves, or if they do they are not allowed to say just yet! 😉 Usually the EA employees on these forums only say anything around the time EA is ready to make an official announcement.
Also, the next EP will not come out until the end of this year. Many people are thinking it would probably be a Seasons/weather type EP since that is the one most requested. 😇:eahigh_file:
That said, while I would love a Supernatural EP like we had in TS3, I think it is much more likely that if they are going to add more supernatural types of Sims to TS4, they would probably make another Game Pack (GP) like they did for the Vampires GP. 😎 If they do this, they might add a GP for Witches/Warlocks/Wizards, and/or another for Fairies, and/or another for Werewolves, and/or another for Zombies, and/or another for Mermaids, etc. This would ensure that each type of supernatural would have more detailed gameplay (like TS4 Vampires did as compared to the TS3 vampires.) 🥳 Also, keep in mind that we usually get 2 GPs each year, and we just had one released last week (Jungle Adventure) so if there is going to be another supernatural GP like Vampires, it would either be at the end of this year, or in another year.
They could also add some lesser supernaturals as part of another pack (like they did for the Aliens that came with the Get To Work pack), or even in an update (like they did with PlantSims in one of Jasmine Holiday's event challenges.) 😉
Happy Simming! 🥳
