The thing most people dont seem to get about LoS is that it is not the "New Castlevania" as some people are raging on about.
For now? Sure, its the current Castlevania. But sooner than you think, it will be a memory, and Konami will move on.
Cox has stated a few times he does not want to be "Mr. Castlevania". He wants LoS to be short. Not a long running series. And it shows. Right from the start they ALREADY have so much shit crammed into one story, AND a foreshadowing epilogue.
Im going to call 2-3 more games, and thats it.
After that, who knows. Maybe they will go back to IGA, maybe they will do another take on Castlevania. We know for sure it NEEDS fresh new blood. a fresh new take, and I suppose as far as being a Horror game goes, LoS isnt as keen on that. I would certainly love a more gothic horror take on Castlevania, with a new story and new everything. And high quality. Like, LoS quality.
But one thing is for sure, LoS wont be forever.
