I doubt it, only because Dracula is alive and well before this game starts. Remember the order was formed to combat him because in the absence of a Belmont, Dracula's minions are waring on mankind.
I think it will be more along the lines of the old guy being a villain working for Drac, Albus finding out and taking the dominus glyph to destroy Dracula. I get the feeling that this Albus guy will turn out to be quite a hero, and I have a sneaking suspicion that he may even be the first Morris to wield the Vampire Killer. Just a hunch based on his character design, his character design very intentionally western.
