December 2016 patch notes were 13 days later than december 2015 patch notes.
So I guess it will probably depends on it they rushed an update with just tradehouse fixes and packages for stores approval or if they decided to work some content into it, if there will be a mid-january or end of January update (assuming the packages aren't in the current update yet) .
Though with valentine's day on feb. 14th and packages usually lasting 14 days, the latter would get close to back-to back packages...
