I know a lot of people don't follow "canon" but whenever I play the game properly I play as "Trailerkiin" (Nord preset 1), the guy from the trailers and the background of this site. I'm always wondering what choices would be considered canon which is why this interested me
I've recently started doing a canon playthrough of Dawnguard, following the Dawnguard faction questline as joining the Volkihar seemed far too evil to me to be canon. I'm at the point where you are about to enter the soul cairn and Serana suggests either soul trap or becoming a vampire lord to enter. I chose soul trap and I noticed that even though you are not a vampire lord, during the conversation with Valerica she says the words "Whether or not you've become one of us in order to survive the soul cairn you're still a vampire hunter at heart" basically talking to you as if you ARE a vampire lord even though you are not. It is clear what she means here and this to me pretty much suggests that the Dragonborn IS meant to become a Vampire Lord at this point lore-wise. It's way too much to be just an oversight or a mistake by the programmers surely?
If the ending of this trailer is anything to go by I think it's a possibility:-
