That's assuming September is a major update, we're yet to hear anything meaningful about that or literally anything at all really... For all we know they'll announce that Bungie in fact didn't really have a plan at all after leaving Activision or we'll hear that now that they've left and have little resources, they can't afford to make the big expansion we deserve after waiting 9 months after Forsaken with no story progression unless you count the tiny bits of conversation between the Nine and their emissary. They either do something Nas good as or better than TTK and Forsaken or they do nothing and destiny dies forever and that will serve them right.
