So, I have been have discussions with people I know on what's next for Chaos.
At this point, Fulgrim and a revamp of the Emperor's Children line (New Lucius and Noise Marine models/upgrades) are coming in 10th Edition.
Also, Huron Blackheart is probably going to get an upgraded model very soon (much needed).
GW could have Kranon and his Chosen return as MTO.
After that, there are a few options.
- Word Bearers: Daemon Primarch Lorgar and 40K versions of Kor Phaeron and Erebus.
- Iron Warriors: Daemon Primarch Perturabo and an updated Warsmith model. Maybe give Honsou an official model.
- Alpha Legion: This is tricky. A model of Alpharius/Omegon would be an obvious choice, but perhaps there could be a model that serves a role similar to Exodus in HH or Phocron from "We Are One" - any Alpha Legionnaire can assume the mantle. Would be nice if a named model could serve as a Champion of the Legion. Sucks that Lord Arkos never got a model.
- Night Lords: Have Daemon Prince Krieg Acerbus get an official model since he apparently is the leader of the largest Night Lord warband in 40K. Update the Night Lords Chaos Lord model and/or a new Jump Pack Lord.
- The Fallen: Since Luther is free, why not give him a model? Also, give Marbas a model:
Who wouldn't want to have a model of that?
A revamp of the faction would be nice with new Fallen models (maybe a proper codex?).
- Rando CSM Warband: White Dwarf could cover this.
As for their loyalist counterparts, I expect Lion El'Johnson to get a 40K model soon.
