Hahaha let's get ready for a Dracula-less Castlevania series :I'm calling it!:
Not that it would be the first for the series, in a manner of speaking.
However the whole Castlevania (sub)series without Dracula would be strange. And even, if it would be good, some (overly devoted) fans will foam at the mouth because it will be too deattached from ideal Castlevania they've built in their heads.
