I don't think the timelines should be connected nor do I want them to be. Why do people insist that there be a connection between the two!!!?
You mean like, beyond all the references made in the games, with character names, item names, enemies, plotlines and what not?
To be completelly honest, as much as I'd have orgasms if the timelines turned out to be one and the same, I doubt it'll happen. People (like myself) insist on it because all the uproar caused by this reboot would turn out to be unfounded, and the whole thing would give us a completelly new perspective to the story, and
maybe give it new life to continue the main plotline. Everyone wished that the canon Castlevania timeline received a breath of fresh air, instead they gave us a completelly different game (That IS good, IMO) with the name "Castlevania" slapped on the title, and a bunch of references that would make no difference if given another name (Rename "Veros Woods" to "Dead Forest" or rename Olrox and Brauner to "Vampire Lieutenant" and "Vampire General" and tell me what difference does it make?). We all know that LoS was developed and marketed to players of the new generation. Imagine if it turned out to be an awesome gambit to make the new audiences start seeking the classic games through a plot twist of sorts, while also opening way for new games to come following the old timeline, now with LoS details added to the mix?
That's be BEAST.
The thing is that we want the old Castlevania to be fixed on where it was not so good, and to evolve. Lords of Shadow brought this hope and quickly whisked it away from us. Deep inside, we all wished that LoS was canon, but it isn't, and we keep on wishing that
something will make it canon.
