A remake of Dracula's Curse. At one point, in a interview about DXC, Iga said that he wanted to do some more remakes in the future, and since he loves Dracula's Curse so much, most of us have assumed he would remake CV3. Only speculation, but likely speculation.
I've never heard this. Where did you read this?
At the Castlevania Dungeon, somewhere waaaaay back in the forums, in an interview, probably very dificult to track down now.
