When's the update take your guess

Although it is unusual after the series of new events coming with just a day in between or so, I guess it will take another week. Usually, big events take a month, and they never end on the day that provides the theme, in this case Halloween. There is always a time span of 10 days or so following that particular date. So, calculating from there we should get the update in a week.
I'm glad to know if anyone has more precise figures than me regarding the duration of major events, I just recollected from my previous observations.
