New allied races: Zann'esu clan of frost vrykul for alliance, Mok'nathal the half-ogre for horde and arakkoa as neutral AR.
N'zoth is defeated. His body destroyed with beam of origination, but his essence is sealed within the Blade of the Black Empire. Sylvanas will steal the blade and what she is about to do with it will be plot to the next expansion.
Talia kidnapped by Nathanos. Sylvanas would use her to threaten the Lich King. Loyalists would take part in that, but in the end they are will be betrayed.
Heart of Azeroth can not be used for healing of the planet. Ny'alotha invasion and N'zoth's release will cause too much damage to the world. Magni and Mother will realize that the world soul couldn't be safe within the planet and it needs to be relocated to another safety world. With Heart of Azeroth we will teleport world-soul of a titan to Elunaria, sanctuary of Eonar. She will stay there with Magni and other defenders.
9.0 - no new class, but the old ones will get a big development and new specs.
Outland, Northrend and old world revamped.
Level squish to 60. Northrend and Outland is 60-70 content.
Most of the content and zones of vanilla Wow to BfA will be turned into legacy state. It will be available, but leveling in old zones would be impossible and with dungeons and raids it will be scaled to level 60. Old loot will have no stats and will be turned into cosmetic.
Major feature is 2 new faction to choose: Harbingers of Chaos(Capital city - Black Temple) and Keepers of Order (Capital city - Ulduar). This meta-factions will unite players from both Alliance and Horde. This choice would be important to your game play and lore experience.
Harbingers led by returned Illidan will fight with Radiance Crusade and Yrel in Outland, Keepers led by Khadgar will fight against Helya and Yogg-Saron servants (and also Nerubians who now serves him) in Northrend. Both new factions hates each other and trying to fight the enemy on it's own way. They will try to spread their influence across Azeroth which cause new pvp activities around the world.
Hunting for the Dragon Isles is another expansion feature. Wrathion will ask for your help and equip an expedition (weekly-type scenario), where we will inspect various places on Azeroth were the Isles could be.
Lairs and Trials. Lair is a "kill everyone in a cave" type thing. Trials is "surviving the waves and killing the final boss " type thing. Warfronts will be improved to make them more entertaining.
New artifact will be another necklace but special for each class with story development. Instead of Azerite/Artifact power, you'll be collecting souls. Each absorbed soul will increase the power of the artifact. Also include's new class halls. Progression system will be similar to Azerite essences system.
Alot of new stories, zones, quests and world activities. World quests will be improved and turned into something new: added more mechanics, scenario-typed WQ and affixes for zones, mobs and player. This expansion is like a completely new game. World of Warcraft will again be the WORLD of Warcraft.
