I wonder if they follow some sort of "Event Calendar" or something, so they know what to release next.. Tortodrones again..? Black Kat Event? Aprocrea? Or some new event? I think we might see a new event in the next few weeks, since it seems they don't usually go over like a month or so without doing a new one.
What do you all think the next will be? And when?
What we know about the event schedule is listed at each event's wiki page: when the event has happened in the past. You can try to extrapolate from that information, to predict the future. But that's all we know, until an employee of Grey Havens chimes in.
Of course, if players enjoy speculating, then let the speculation resume. :)
