Here's my prediction: Year 1: Atheon, Crota, Skolas Year 2: Oryx, Cabal Fleet Commander, Quaria (Ancient Vex Mind) Year 3: Champion of the Darkness (Plague of Darkness Raid), House of Kings' Kell, Cabal Vigilante. Year 4: The Great Machine (Fallen Servitor Mimicking the Traveller), Nokris (Hive God), Vex Time Manipulator Year 5: AI (Charlamagne or Rasputin), Vex Reality Manipulator (attempting to simulate reality), House of Rain (ancient, Darkness corrupted Fallen) Year 6: Ahakmara (non-Darkness), Xol (Dark Worm), Imperial Cabal Legion. Year 7: Cabal Emperor, Vex Manufacturer (forward/backward in time), Ur (Dark Worm). Year 8: Taox, Savathûn, and Xivu Arath; Psion Rebellion (you're helping the Psions), True Kell (finding Kell of Kells) Year 9: Taken Akka, Eir and Yul, The Nine Year 10: The Darkness, the Rebuilding (City-based Raid, breaking final alien presence in city and on earth). End of Year 10: the Traveller. This is based off the assumption that the end of each year results in a massive DLC, plus two smaller ones.
