nobody knows??? and what new games will come out to add to official story line of Castlevania this is so far that I found
Not all Castlevania games are offical parts of the story, for example,
remember that Vampire Killer [MSX], Castlevania [NES], Haunted Castle [ARCADE],
Super Castlevania IV [SNES], Castlevania [PC], Akumajou Dracula [SHARP X68000],
Castlevania [C64], Castlevania [AMIGA] and Castlevania Chronicles [PS] all
share the 'same' storyline, they all fall into the same 1691 date, even if the
games are different.
The official 1691 storyline used by Konami is from the Castlevania [NES] game.
Same goes with Castlevania Dracula X [SNES] and Akumajo Dracula X [PCE],
they both share the same 1792 date, even if the games are different.
The official 1792 storyline used by Konami is from the Akumajo Dracula X [PCE]
game.
