It would also lead into more faction interaction after BFA (which has also been implied).
The leak I mentioned was posted on 4chan to start. Reposted for convenience.
Plays into theories that the Heart of Azeroth is the Dragon Soul (similar look, getting pumped full of Dragon Powers as of 8.2) that we found in Zin'azshari in the first place, and it may be part of a timeloop if we leave it behind in 9.3's raid. Also it looks to be a Dragon/Old God heavy expansion with zones and raids based on Deathwing, Y'shaarj and the Infinite Dragonflight. Cosmetic Classes (that's what I assume the Prestige Classes are) that include Necromancer and Tinker as the new real class also sound plausible because of fan demand.
Zin'azshari is also a huge part of the lore that is mostly just a tiny zone in Nazjatar, and I wouldn't be surprised if it comes back full-force to get Suramar points.
The one thing that makes me think it's bullshit is there's ZERO mention of Dark Ranger whatsoever
