Castlevania went through a pretty rough patch after 2008’s Order of Ecclesia.
While the original Lords of Shadow was a fine God of War-like romp, it was far removed from what made the series famous in the first place, and the sequel flub kind of put a kibosh on the whole idea of a 3D Castlevania. Mirror of Fate sort of course corrected (and served as a prelude for the better Metroid: Samus Returns from the same developer), but by then the damage had been done: Castlevania has been dormant for nearly five years now.
But Konami will never, ever pass up the chance to resurrect the classics.
