I already want more details. It sounds like they took it on the chin, which was to be expected given the situation, but... yeah. That's it for the Blood Angels and their successors as we knew them. I doubt they number more than a single full chapter between them, and some of those are going to be from the Chapters that were more/too influenced by the Flaw.
I think it's going to be similar for the Space Wolves. Having to dilute their geneseed and accept the Primaris because there is just no other damn choice other than to die out completely.
Ask not the Eldar a question, for they will give you three answers; all of which are true and horrifying to know.
