I'm beginning to believe that Mavado will be the next reveal. I came to this conclusion with some help of a post (on another site) by EMPR Twisted.
1. The recent Retweet of Kimye. Kanye is wearing a Trenchcoat.
2. The "Taxi Ride Business is tough" in which within the article it reads "...competing against more entrenched players..."
3. Red Dragon appearance in the Comic book
4. Of course the Boot pic shows a player in a trench coat or cape.
There were others like the fasteners walmart pic (which was off a hook) and the "Listening to Destiny's soundtrack by Bungie (Mavado's Bungie cord like move) and though that may be a far stretch I credit those hints to EMPR Twisted.
I'll keep a lookout for HOOK or WATCH like tweets but to me it's looking like it's leading right to Mavado
