I haven't been to the grotworm lair yet, and I don't know a whole lot about this update, but the screenshots of the lowest level remind me of the teaser images. Bottom three images here (in case they don't load in hide tags) [hide] [/hide] Those screenshots could be from the third floor but I'm not sure. If they aren't, then it's possible that they're from the fourth. Oh, and I think that most doors, stairs and other things are put in the game to keep us interested in the future. Look at how much people speculated over the frozen door in GWD. It's a self sufficient hype machine.
