I was sure they said they were going to start letting us know sooner. Recently we have been given a mere few days. Seems to be going in the opposite direction.
Please support my Quality of Life Suggestions here:
There is no official announcements for all future events, they go about a week before the event start (because planning can change at last moment and forums become flooded with complains).
By predictions next week at thursday(usual starting day) should start "new life festival", if it is not on 16 it goes for 23 and should continue to somewhere at january.
Somewhere at the beginning of next year (Q1) - clockwork/morrowind/summerset (aka daedric war celebration), next should be some new version of MYM (pvp)...
It is nothing officially announced and only predictions based on PTS and previous years...
