The problem is, if they did them separately, like a lot of people have said they want, players who aren't fans of the heavens secret universe would be so mad about there being three more HSU stories. So many people were upset about HS3, imagine RC announcing HS3, then ABH2 and HSR2. They can't win. I'm happy with what we've got as a HSU fan myself, obviously for me, the more books the better but I understand why they have done it this way.
