And in many ways, yes, I agree with him.
New boss fights against a large moth and/or dribbly guy is it?
New weapons is it?

New activity to grind to up my power level by +1 every week is it?
Everyone would tackle the new stuff in a similar order, then round things off with the inevitable Raid.
Some scenarios, an absolute nightmare, but hey, I respected the twists.

Seasons are changing, too.
Instead of three Episodes, Bungie will release four Major Updates per year, one every three months.
They’ll include new activities, rewards, weekly events, and meta/balance updates - all free.

Other than that, though, there isn’t much more information.
I think it’s always been best in, for lack of a better term, funky little packages.
Most notably when they introduced a horde mode - I miss it!
