Umm... the story I remember reading about Lords of Shadow from its website didn't sound anything like Castlevania. There was no mention of Dracula, the Belmonts, or anything you would associate with it o.o
I remember it had something to do with Christmas. Weird o__O
That'd explain the Kojima style.
Maybe it'd be intertwining stories. Gabriel wanted revenge for some shit, he learns his threat has ties to Dracula, while Alucard is dealing with whatever is going on that also has ties to Dracula.
I sincerely think the game announced at TGS is also this game, as the game has now vanished like Lords of Shadow did the moment the game was announced. Maybe the announcing at TGS was announcing LoS for Japanese release, but the kinks weren't down yet.
Yaknow, like how Sonic and the Secret Rings was called Sonic Heart of Fire or something similar for like, a couple of weeks?
