I think it might be sooner, but as you say, its now around 30-40 net caps per day so will take some days to finish off the world. Unless those inactives go barb ofcourse.
I think its too soon to name a villa, but lets start with the timeframe ( mikey gave a good example).
Heres my estimate:
I think its safe to say TLA will win the world, so there is only 11000 villas to be nobled. I will assume around 25-50% will go barb, so that leaves about 7000 villas to be conquered. Current rate is around 30-40 villas per day. Leaves me at 7000/35 = 200 days from now.
No need to make clean calcs, its roughly 6-8 months from now. I go for the max, so I say July 2011.
Edited :
Hmmm, i misread the update map: it seems TLA nobles around 170 villas per day.
this means 11000/170 = 65 days. I would say by the end of february...
