GoodGuyA: They said they would, but they need to fix the game proper first.
Do you have an official source of this? My worry is that with the Djinn editor they already had a good foundation since it was based-off Bioware's NWN engine and included Aurora editor. Also, NWN's construction was tile-based.
As cRPGs gets more advanced and the topography and construction of the gameworld gets more complex, editors follow. To modify the internal toolset used by the team so that it could be released to the masses then becomes a more daunting task.
