There is no ETA at this time.
The reason is everyone that is working on the project got preoccupied with other stuff. For me it was my main job that drastically reduced the time I could spend working on Dungeonbuddy.
The ETA given by Kickazz was based off the how quick I scripted the LK dungeons and I had that week off from my main job and it didn't include the fact that most LK dungeons are easier to script then Cata ones and that there still are core features that needed to be added to DungeonBuddy such as an avoidance system that can navigate around bad stuff e.g fire on ground (I am working on this atm) and a mode for farming old content.
thats all cool and all much love.
but why not release HB without dungeonbuddy for now so atleast other stuff can be fixed? as they said they were waiting for dungeonbuddy to release the new HB
