What "Festival of the Lost" kind of event do you think Bungie will do for December?

I'm hoping we'll have fake/dead trees and mistletoe, with Eris confused as to why we have dead plant life everywhere. And some sort of classless helmets with red hats or suspended mistletoe above us. Maybe it's too similar to how we do Christmas, but Halloween is basically going around to your neighbors in masks receiving candy. Sooo... similarities acceptable. But what do you guys think!! I'm a curious guardian.
