PS3 Gamer here - ( My official this has probably been written before warning )

I just wanted to say I LOVE the attention to detail that went into the Dawnguard expansion.

Several monthes ago I wanted to explore the Dark Brotherhood and magical/ vampiric aspects of the game, so I made a new imperial male I lovingly dubbed "Drakulya"- the name couldn't be more fitting in Skyrim from a role playing sense as well, meaning "Son of the Dragon" - and have played through level 30 ( My current level with him ) PRE dragon invasion. To clarify, I lead the Dawnstar branch of the Dark Brotherhood, ( Lets hear some love for Babette! ) but I have yet to deliver the dragon stone tablet to Whiterun.

Having heard there was some kind of undead dragon of some type I was a bit weary of what to expect when I encountered him, would I absorb a soul or worse yet be granted unseemly early access to a shout?

No.

The dialog was beautifully written to make my characters as yet hidden destiny as Dragonbron a tantalizing clue and dropped at that.

Maybe some day we WILL learn why the Dragons instinct was to call me Dovah! LOL!

VERY well done Bethesda! Its attention to details like that that make a game so treasured and loved!
Thank You!

Unfortunately, they didn't do the same with vanilla, where several people call you the Dragonborn even if you didn't even start the main quest.

How so? I don't ever recall that.
