One thing I'm concerned about this point is what parts of 1.X will remain what we'd technically call "canon". Press releases and forum posts are kind of bi-polar about this issue, with the impressions being given that we'll "return" to the original storyline, which has been heavily "changed," with certain elements being "scrapped."

This is complicated because, yes, the game is being relaunched and rebuilt, but also what happened in the Sixth Astral Era is still technically history?

Just how much of what we went through is going to end up on the cutting room floor?

As for the nature of aether and primals and such, I think I'm about ready to make a post on that. Wrapping up some loose ends.
