Glowing eyes and the earlier mentioned new feeding animations. My guess is a Vampire based DLC. Guards of Dawn? Dawn = Just before sunrise. So, they're a daywalker breed of vampires, a powerful cult that hides amongst mankind? Or a group that protects Skyrim against creatures that lurk around before the Dawn sets in. What about the Snow Elf prince? Is he leading the Volkihar Clan? They too live under frozen lakes and icy tombs.

Crossbows are a sure way to a Vampire's heart. Easy to fire, not depending on a straight bowarm and stereotypically used in slaying Vampires. If this Dawnguard hunts Vampires, they probably have those crossbows.

If this takes place in Dawnstar, it may also be the start of each city having its own problems and storyline. It definately makes up for lack of city quests, as the Jarl's currently need you to only solve small tasks. Walking dead and huge labyrinths for Falkreath? Family feuds turning civil war in Whiterun, introducing a politics system? Unraveling the secrets of Winterhold? This could offer for some interesting DLC's.

But let's wait first for what this DLC will offer. I hope new content in the range of armours and weapons will appear also. It probably will, even if only a quest item set.
