These rumors validate that things are moving forward "flyers are close", and "Chaos codex was done", but they seem to all be concerned about the arrival date of both releases.
The dates on these rumor bits appear to be speculation after taking into account the rumors by Neil Kerr aka Skcuzzl listed here. http://www.natfka.blogspot.com/2012/07/new-chaos-rumors-are-here.html
Just got some info from my regional distributor. He claims the next wave of flyers is close. So perhaps no CSM after all.
my source told me that the Chaos Codex was done, had been circulated around head office and was due for shipping this week. However, it is possible that they could release it September 1st with Flyers for August
