There's still art, coding, design, texts etc. going on. :) When the QA starts, nothing new can be added, only bug fixes. When QA gives thumbs-up to the update, it gets sent to the stores for approval. Then we need to wait for it to be approved. How long it takes is something I can't say since it varies.
You'll have to wait and see about the event! :D I don't usually comment on these things since plans may change down the road and then players could be bummed out. New events can not be added via maintenance breaks. They require code changes which require a proper new version of the game. We can do some minor tweaks to them via maintenances, but not add a full new one.
Yes we wanted to organize an AMA for the next update, but had to cancel it since too many team members are for example travelling around the update and it just isn't doable. However, we will arrange more AMA's this year but we haven't decided when.
Cheers,
Nick
