AMA with Bungie Dev About On Disc Content.

I can confirm that there were sudden and abrupt changes in the development of Destiny less than a year ago. There was tension between higher ups the entire time we were developing the title due to a lack of cohesion about the vision for the game. One side wanted this huge space epic, like an MMO Mass Effect and the other side was not convinced that would sell and wanted to pare things back to more "easily accessible" standards. They were afraid too much story elements and cut scenes would drive players off.
