Note though that the video contains some very big spoilers regarding the new questline, walking through much of the beginning as well as the end fight.
I don't think that I'll be playing DDO myself. Primarily because I have no desire to slog my way to level 16 in the game and in part because I've got plenty of other games to keep my busy. But I'm kind of sad that I won't get to experience any of this drow content myself.
I just don't think that the hope of maybe seeing a glimpse of Eilistraee in the eventual expansion is enough reason to start playing the game.
Note that next to the video there's a whole article describing the update at the original link.
