Many of you believed "if not this update, next for sure" will bring significant changes for this game, making it better, but it never happens and never will. Altering this game to the expectations mean all what have been done so far was a great failure and none of them will make this decision.
It's not only a problem about new content, but about future, which is empty... when you will time travel to for example Christmas - you will experience NOTHING, just a regular day.
It's still quite high probability Big N will provide update, and most of players will be overhyped again, because of some events, forgetting it's exactly copy-paste of previous ones.
Best move would be just to complete all permanent events / holidays as we had in previous iteration, announce burial of this game and let players to play in game as we have and stop expecting miracles, as they never happens.
