Basically it was a user who claimed to be the usual Castlevania leaker, PORTRAITofRUIN, proclaiming the title of the game, and it having two protagonists while naming them. The female was named Miriam, and I already forget the male's name.
We'll find out on Monday if that leak is true. I personally doubt it, as anyone on /v/ can act like they're anybody, especially when they don't post any leaked materials. She usually posted ingame stuff on GameFAQs until she became reliable enough to just take her word for things, but on an imageboard like /v/, there's no way to vet if they're the same person..
