As a modder, Lar_q's comment is adequate enough. I understand it from a development position.
I'd rather have those three quality dungeons (The Knight's Dungeon, the Inner Sanctum (Temple of the dead), the Druid Dungeon) as opposed to some crappy ones and I don't care if it was promised. You guys are way too anal about things in the face of a game which is otherwise top quality especially in an industry full of games way too short.
You guys also forget that the dungeon was never a priority. I can imagine Larian forgot about it entirely hence why they never wrote an update about it.
