Updates seem to flow out once a month or so. I expect late January myself. Big content updates have happened in Dec 2014, June/July 2015, and Dec 2015 (so I'm not sure if that holds any pattern) but smaller bug fix releases occur each month or thereabouts.
The seed "Golden Apple" (without the quotes) has a decent size village in the center map if you want to check. It also has another village 1 map down and 1 map to your left of the center map. It has a 3rd village 2 maps to the right and 1 down from the center as well.
