Okay Guardians just going into this none of this is confirmed and is speculation from the strikes. I am beginning to believe that the next raid will not be a cabal raid but instead a more hive oriented raid. I believe this due to the fact that many of the strikes are focusing around hive and taken and centering on one main character Savathun, Oryx's sister. Savathun has also had contact with a Leviathan (Check vanilla destiny books of sorrow). Savathun has been mentioned in the strike Savathun's Song and in a strike in the EDZ the cabal has been recently taken. While no known creatures aside from Oryx, the taken king, are known to be able to create Taken, it is reasonable that Oryx's sister would have the ability to take. Now how she controls a Leviathan who in the book of sorrow were allied to the traveler is beyond me. Let me know what you Guardians think of this idea and feel free to comment below. Be Brave
