I noticed that some of the statutes in the vampires GP were fairies. I don't really believe in hints that are in the game like furniture. But who knows? Maybe there will be a supernatural EP
I think in this case they were trying to avoid any religious connotation by using fairies instead of angels for the statues :) but I hope we'll see more supernaturals in the future. Especially if they're fleshed out like TS4 vampires (I wasn't a big fan of fairies in sims3).
