Best news I've heard from the Konami camp for years (since Gradius V was announced probably). I'm all in, with or without Castlevania branding.
In any event, that lead character looks like a PROPER Belmont: grim-faced, weather-beaten, and of course with that all-important chain whip. I think this may even have started out as a next-gen (hate that term) Castlevania proposal, and Konami realise they have something more perhaps, or maybe trying to target a new audience in addition to the CV crowd.
If this isn't Castlevania related, more power to Konami. I say go for it if that's the case. Let's evolve, let's have new IP. Arguably the game flaunts the kind of change Castlevania itself needs: a step away from the restricting canon of the series and a delve into more mature themes.
