Well, I've got to redo pretty much EVERYTHING atm. The 3rd version is blocked out about 3 quarters now, so once I've got that done, I'll start on details, doors, elevators etc, then textures, then NPC's, followed by models and effects and the likes, and eventually scripting in the objectives. So for the proper final release, we're talking upto 3 months, because I work full-time and have an active social life, but I do intend to get it out speedily, as this map has been as much a curse on my life as it has an act of artful blessing.
Check the album, theres a new version of the map blocking in GTKRadiant I've just taken. Theres a few differences, but the layouts pretty damn close to version 2's.
