I was poking around my inventory in the Destiny app looking for items to transfer between characters, and I noticed in my sparrows that there was something that doesn't belong. There was a blank space titled "Classified". I opened it in the app and got a message: "All will be revealed in time, young Padawan". If you've watched any videos or dig around for Dawning secrets, you'll be familiar with that message. Bungie seems to be using it to hide items, and with the Paper Fortune Grimoire's hint at New Year's presents, I think that the fortune will turn into a sparrow on New Year's Day. I'll try to add pictures in a bit, the app won't let me do it from my phone.
