Bungie can't realistically make a TTK sized expansion that was as good as TTK starting from when Destiny 2 got delayed. They would have to borrow some stuff, in particular new geometry and a new enemy type, from what they already have for Destiny 2.
I agree. The context of how the community sees it will have a lot to do with whether we know when Destiny 2 is coming or not. If it's already been announced by the fall as a February-March 2017 release I think people won't expect as much. But if we're still totally in the dark, and it's a disappointing release, that's going to be rough.
edit: Top of Page! Capcom is rereleasing RE 4, 5, & 6 (in reverse order for some reason) on PS4 and XBO. RE6 gif to celebrate
