No mention of any of the Imperials picking up the 'Fallen' bit either, and "He might not recognise his person but he did recognise the blade Cypher carried on his back, the sight of which made him shudder with dread." sounds like we're going to get another 10 years of speculation on what the hell that sword IS. So Dark Angels storyline... just about the only one not exactly advancing.
As for the Blood Angels taking it on the chin... Again... News at eleven?
Ask not the Eldar a question, for they will give you three answers; all of which are true and horrifying to know.
