More details are coming out on the formations and other information for the rumored Chaos Marine codex that is on the horizon. While some dates are coming in, I still suspect that the 40k turnover is on the horizon towards the end of the month. What that will be at this time.... well we will have to wait to find out.
Please remember that these are rumors. This is a continuation of previous rumors that were posted by TheHairySorcerer20. You can see these here if you are just now catching up. http://natfka.blogspot.com/2015/09/chaos-marine-codex-coming-soon-with.html
