No announcement unfortunately, just the question for ZOS when the event will start? Today would have been the most likely date, considering that events usually start on thursday and anniversary event needs to take place directly after Jesters event (so next thursday?). Additionally, Jesters usually includes April 1st and anniversary April 4th, which can't work out with a start on thursday for both events anyway.
So, what's the current plan? Ditch the thursday release and have it start another day (tomorrow and for one week until April 1st?), or have anniversary event start later than April 4th?
Or is the same reason the Explorer's event wasn't extended, to first sort out the problems caused by the latest patch and both events are postponed until the servers are a bit more stable?
Whatever the current plan is, ANY information would be appreciated, even if plans might still change down the road. That's not the improved communication regarding event dates that was promised long ago.
