Another possible avenue is things were cut/rearranged and are being released over time, even before or in between the DLC e.g. Queen's Wrath/bounties or Raid or Iron Banner etc. No one knows what Bungie's plan is for the next 3 or 6 or 12 months are exactly. They could be releasing a shit ton of content or story or weapons or areas or missions or characters.
I have to agree about the speculation of development hell, I posted as much months before the game released myself. I also think releasing on 4 platforms took its toll, the studio has mostly been a one platform studio for a long ass time.
Overall I'm still enjoying Destiny, the world and that gunplay hits the sweetspot. Great value for money but does disappoint in the story department.
