All we have is a name, well a name and a logo, from the US trademark database for Castlevania: Order of Ecclesia. I doubt Konami registered this for laughs so this is probably the name for a new Castlevania game. Could this be the Castlevania game for the Nintendo DS Igarashi-san hinted at?
Just to throw this in for discussion “Ecclesia” is a Greek term for a gathering of citizens. Usually it’s linked to theology and now vampire hunters.
