Oh god, no... not Bioware DLC...
Bioware does many things right, but DLC isn't one of them. Sure, they occasionally do one right (some of the ME2 ones were pretty nice), but other than that it's just an overpriced quest chain with some recycled environments. Seriously, these are the people who made "Witch Hunt", one of the worst pieces of DLC since the Oblivion Horse Armor.
Those images are hinting at a 1-2 hour quest that will cost you $10, give you some overpowered items that screw over the game balance and have no impact on the game itself. If you're lucky, it'll be a stand-alone (like Leliana's song), exploring a side stories of people other than Hawke and will be a functioning narrative.
I think I'll pass on the DA2 DLC...
