Is there a timeline for the release of certain milestones for Endwalker?

I never really paid attention during the prior expansions, but seeing Ubisoft do this with Assassin's Creed Valhalla made me wonder if SE does something similar and I just haven't noticed it.

Do they have a timeline for the release of certain pieces of information? Like I know there's probably a live letter happening...sometime, and a video where they show off the new moves of each class, and maybe some other things, but I have no idea when these things are, and was hoping maybe the community could help point me in the right direction.

Or maybe they don't do this and no one knows!

I think the media tour was septemberish? Most of those things would show up around that orbit.

The timeline was vaguely explained in a live letter, saying what month events would happen but not being more specific than that except for the release date.

There is a Live Letter Mid-september to accompany the media tour that is touted to go over battle system info and another early November to go over other details.

At least that was the plan as of the last live letter.
