Dishonored: The Knife of Dunwall DLC Announced

Those of you who are interested in more Dishonored story-based content will be pleased to know that Bethesda has announced a new DLC, The Knife of Dunwall, starring supernaturally gifted assassin Daud (who some of you might remember as one of the game's antagonist). The DLC is coming April 16th for $9.99/800 MSP and will apparently be the first of two add-ons covering the side character's story:
Features of the new DLC include:

New Powers, Weapons and Gadgets The mark of the Outsider empowers you with unique supernatural abilities. Call upon the Whalers to assist in combat with '˜Summon Assassin', track down hidden Runes and Bone Charms with '˜Void Gaze' and learn to use new variations to powers, including '˜Blink'. To aid in your dangerous exploits your customized arsenal of weapons and gadgets will include Chokedust to daze your enemies, whale oil powered Stun Mines to shock your targets, and a concealed Wristbow to launch sleep darts and explosive bolts.

Explore More of Dunwall Make your way through the Legal District and infiltrate the Rothwild Slaughterhouse, a steaming factory filled with colossal whale carcasses and their hulking butchers. Revisit the decaying Flooded District, the location of Daud's hidden base, first seen in the original game. Return to the scenes of key events in Dishonored with a new perspective, including the fateful moment that sets off Corvo's journey.

Choose Your Path On your search for answers, approach each mission with your own style. Your redemption or your turn towards darkness depends on your skills and the decisions you make. Discover the mystery behind Delilah in this stand-alone chapter, and then conclude Daud's story in the upcoming final add-on, The Brigmore Witches.

I'm personally interested to see how close the DLC will be to the original in terms of level design and gameplay, and in what ways it will differ.
