[quote]Who decides what the "core game" is? Who is the one who decides how much story to tell?[/quote] You basically summed up why I feel like this is all conjecture. If Bungie comes out with DLCs that really don't tell much of the story, then what? Is it because they are saving it for the sequel to Destiny? Is it because they ran out of time? Is it because they suck at writing? Who knows, except for Bungie, what is complete and what is core? And, it's unlikely that they are not going to spoil the surprise (if there even is one.)
