Looking at the new weapon branding from E3 with things like the suros weapons and omalon makes me think that these could be potentially be new factions with the taken king or New vendors. Another thing that caught my eye was that the titan in the trailer was wearing gear from Hakke so this makes me believe these vendors may be selling armor also or this could just be new vangaurd stuff. I would like see if other people agree with me or have their own standing on this.
