In the googledoc, Emeralds "Only generates in Extreme Hills biomes" is listed as "needs" adjustment. What kind of adjustment are we thinking? Will they someone generate in the main world (outside of a regen world edit)?
Main world probably won't ever get reset because of problems with towns. Therefore emeralds will probably only be found in the mining world.
It is turning 1.3.1 as I type. You can update to 1.3.1 and play on ECC with the 1.3.1 update tomorrow.
Of course they are never going to regenerate the whole mainworld. My question is this: If you buy a WorldEdit Town Regeneration (http://www.ecocitycraft.com/wiki/in...+)#WorldEdit_Town_Regeneration_-_.24100.2C000) and you are in an extreme hills biome, will there be emeralds there after the regeneration?
