Chaos Space Marines are the next codex, despite some obvious commentors looking for an argument on just about anything. The date and which month to credit, seems to be of some contention, and here is the latest on just when we will see the Chaos Space Marine Codex.
Please remember that these are rumors. Salt required.

It's hitting pretty hard that CSM are actually October, the confusion amongst the rumor mongers is that word is WD will hit the 22nd, in time for GD UK the 23rd. With pre-orders for CSM within. And on sale date of Sept. 29th. with a later in the month of Oct 2nd wave.
So the CSM out Sept is technically correct, but the reality is its the Oct release.
