Problem is, if Konami says it's a Castlevania game it IS a Castlevania. Maybe by name only, but still every bit as legit as the original NES Castlevania.
Also, careful what you write in these forums. Konami may very well pick up on your idea and make a game of it, lol! 
Name only, but even if Konami says so, to a point, even their say wouldn't matter. If they were so greedy and corrupt that they'd push something like my idea as a CV "just for the sake of milking a new fanbase with an original title masked under the name 'Castlevania' as a safe familiar sell", credibility will no doubt slip from the fans. And I'm not saying LoS could be placed along side my example, or is anything like it in spirit. LoS, at the least, has some CV feel to it.
I mean, if Konami takes a playing card, smears shit on it and says, "We call this Castlevania!", sorry, I'm going to disagree, and to hell with Konami's say.

Anybody who gets that big headed that they can do something stupid like that, and think they can be pat on the back, needs to be taken down a notch!
