Well I see that Toady's back to working on Dwarf Fortress again. So I guess I can perform perdiction time once more.
But this time it'll be a bit different. Because as we all know, Toady's still feeling the left over effects of the flu and despite feeling fatigued, he's braving it out and trying to work on it. Even if it's only a little at a time.
As of right now, he's done the new life and population features of the underground and is currently working on the underground creature civilizations(and body parts too based on today's update).
Orginally I had expected the remaining features to be done in a week and a half. But now that Toady's is still recovering I expect this process to take longer. At this point with his fatigue, it could him about twice as long, but I some people who seem to get over their fatigue with time so the time could vary.
But as of this point I could perdict the underground to be done sometime between 2 -3 weeks. Give or take a few days with whatever is decided on the rope ladders.
Overall though I perdict the underground to be green by anywhere between January 23rd -January 31st. I'll save the final phase where all the test has to be done for later since I'll base it on how well he performs during this part.
Toady, I salute you for braving out the H1N1 flu, and managing to get over some of your fatigue, but don't straint yourself. Good luck!
