Here is another little rumor bit about Dark Angels, and specifically this time not about Deathwing or Ravenwing. Apparently it will also become an option for standard codex Space Marines as well. check out below.
Please remember that these are rumors.

Little birdy told me that Dark Angels Tactical Squads will be able to take a Heavy Flamer as a heavy weapon option. Was also told that the Heavy Flamer option would not be unique to Dark Angels and that subsequent Marine book Tactical Squads would get Heavy Flamers as well.
Another word from the same little birdy as before: The plasma re-roll special rule that Azrael gets is also a "Chapter Tactic" that most characters (excluding named ones) can get, albeit for a points increase (not cheap either, apparently).
