I know I'm late to the game here, but seriously, how could it be any blade other than Dawn?

The prophecy from Lord of Light says Azor Ahai will be reborn amid salt and smoke as the Prince(ss) who was Promised, and that (s)he will stand before the darkness wielding the sword Lightbringer once again.

Whoever wields Dawn is referred to as the Sword of the Morning.

Lightbringer = Dawn.

Osha claims the red comet heralds the return of dragons. Dawn was forged from the heart of a fallen star. So is it not unlikely, in a pure thematic sense, that Daenerys, mother of dragons, having been born amid salt and smoke on the volcanic isle of Dragonstone, will wield the world's only comet-based sword to say the Night King?
