I hope these are true.. faeit 212 posted that all of the major chaos legions would be getting full supplement support and these supplements would actually have more rules content to them. The rumor also stated that all of these are being worked on at the same time and they should be released either at the same time or right after the other. I don't know about you guys but this was the news I have been waiting to hear especially after seeing all of the customization that vanilla marines have now with there new book. The rumor also stated that these books will bring the flavor back to the legions like never before. This I certainly will take with a lot of salt as I have been let down so far by book chaos space marine books. Don't get me wrong, the 2 books are definitely fun to play and offer some options but not to the extent that I would like too see them. I really hope these new supplements are the real deal and bring with it the options that all csm players have been waiting for. Some quick points on what I would like to see per my chaos armies..
Nightlords - bikes and raptors as troops at least. New special characters. Army wide stealth and ways to miss with leadership - terror tactics. A way to make standard csms stubborn.
Thousand sons - better aspiring sorcerers, we are currently paying the same price for these guys as your book standard hq sorcerer. Able to pick other spell lores other than tzeentch like chaos daemons. Ways to increase the strength of thousand sons bolt guns. Better psychic defense. Actual rubric termies.
Iron Warriors/Dark mech - changes to force org. Actual warsmiths. Army wide Tank hunters. New dark mechanicus units. Way to make standard csms stubborn. New special characters
On my painting station currently im working on some screamers, and of course the required Riptide. Let me know what you think.
