A little birdie, that works at bugman's bar, told me that Jervis Johnson himself gave up this little piece of info. He said that the new codex won't be compatible with the current chaos space marines codex. He said that the two would be seperate, so if you wanted to field the new daemons they would have to be taken as allies. He also confirmed that it would be all daemons and lost and the damned. Take that for what it's worth.
GW-Regeln sind nicht immer gerecht, dafür aber meist schlecht gebalanced.
