You forgot to mention that where probably would be a digital reprint of the Sabbat worlds crusade background book - with new stuff up to date till the last book 'war master'. Dan told that. And the map of crusade would be reprinted too
and that is awesome
NExt graphical novel from Neil Roberts and Dan Abnett is now definitely has a green light
Also the vengeful spirit novel could be quite good, or sucks a big time, because I just can't imagine, that some feuodal-technocrat system could be a challenge to the whole Sons of Horus fleet.
And the last novel in this GGhosts arc would be called Anarch - what means that he would probably kill The Lord whose name I'm using for the forums. Here I sign with regret
