Well from what I understand oryx isn't actually a hive God. He is like napoleon, he is a self proclaimed God. There are actually a bunch of hive gods that will come after we kill oryx in the forge of the gods. But, that's just all speculation. It's interesting though that the hive are getting a lot of game time versus the other races. I have also heard a theory that when the queen dies in the taken king, her brother will hold the guardians responsible and he will become a boss of one of the year two expansions. There is a lot that they could do, including intrude more enemy races. One thing to remember, this game revolves around the darkness, which is a race that people seem to forget is in this game, so we could/should see much more darkness creatures as we get further And further into the yearly cycles.
