Do you belive that the Taken King isnt the last hive based dlc? I ask this because in the story mission Regicide, you can scan a statue that is symbolizing the god Nokris. Also I noticed that everyone in the game (npcs) refer to the Dreadnought as "A" Dreadnought, meaning that there is more than one of them. Also too me Oryx does not look like a "King". To me he looks an admiral if you will, he doesnt look like a monarch in my opinion. So my thinking is that King is a term for the hive that means capt of a Dreadnought.
