Well, the succubus-themed Castlevania pachinko game just came out with a new trailer and some character stills. It doesn't look like the red-haired girl turns into the SOTN succubus (unless they've left out all spoiler images of her succubus form, which is possible but I feel unlikely), as all previous images seem confirmed to have been the LoI succubus. (the lighting just makes her hair look reddish instead of blonde in some scenes). On the plus side, there's more vampire Annette.
Also, Hiro (remember him) seems to be coming out with a Papillon Venus doujinshi or light novel. Possibly in collaboration with Sch-mit? Can't really tell from my translation. Anyway, it's out in a couple of weeks and looks cool.
