Would Konami make another Chronicles title, though? Castlevania Chronicles was a remake of the Japan only Akumajou Dracula for the X68000, which caused the game to be finally released in America. Then Castlevania: The Dracula X Chronicles was a remake of the Japan only Akumajou Dracula X: Chi no Rondo for the PC Engine, which caused the game to be, again, finally released in America.
I always saw the Chronicles games as them remaking games that were not localized (mainly due to the fact that they were on inconvenient platforms). In any case, the only other Japan only games I can think of are Arcade and Pachislot, only the former of which would even come remotely close to getting a release in America.
I would love a localization for The Arcade for Wii-U, but I do agree Dracula's Curse is the most deserving of a remake right now for the classic titles, and for the Metroidvania titles, I personally think Aria of Sorrow.
