Anonymous Scandanavia seems to be part of it (adding more riddles). Check it out on twatter.....hopefully he's not just a troll. Several people believe that it's the rest of HRC's "yoga" emails, amoung other stuff....possibly 9/11 related. FBI released redacted emails in batches 1-6 and they referred to them as the "vault". So, if there's a vault #7 that they're withholding, I would assume assange has it, and is leveraging fbi in some way, to gain freedom maybe.
The supposed dates for all of this to come out is 2-19, 2-18, or 3-21.
I hope it's not all smoke and mirrors.
