I came out of the live stream disappointed. I've since thought about it and realized Bungie just did a lot of the things I wanted them to do with Destiny 1.
High on the list of things I wish we got during Destiny 1 was a roadmap for Bungie's support plans. We didn't get one for a few reasons, high on the list being, Bungie's sustaining plan changed several times. Smaller expansions, big annual expansion, micro-transactions supporting events, big spring refreshes of existing content. They didn't really lock into a cadence until the back half of Destiny's life cycle and even then were very hesitant to talk about much until right before it released.
What they did here was outline a roadmap for the next year (~3 month seasons), message the scope of what will change with each season (mostly cosmetic, but also new weapons, armor, MP maps, weapon re-balancing, clan rank resets, etc.), cover a lot of the specifics that are coming with each (The Dawning, Festival of the Lost), show early concepts for things not yet finished (something they very rarely did with D1), and demonstrate they were going to react quickly to feedback with the Iron Banner changes.
Basically, along with the first two expansions, we have a roadmap and support plan for the first year. We never got that kind of clarity with with Destiny 1, and I complained about it quite a bit. In hindsight, I understand better why it never came. But the fact that they have a plan together this time around is just another of the ways that Destiny 2 is starting off on much more solid ground that D1 did.
There was a lot of fluff to pad out the live stream, but at high level, this is something I really wanted from Bungie for Destiny and I think they should get some credit for getting their house in order and setting expectations this far in advance.
Now about that FWC faction rally armor concepts...
