Jotting down my brief and believable story predictions:
9.1 Conclusion - Sylvanas defeated, stands defiant, one-shot or abducted by Elune who magically appears. Jailer released and travels back to Azeroth. Setting up 9.2.
9.2 - Revamped Icecrown for World content and ICC 2.0 for the final raid. During raid, Jailer successfully animates corpse of Galakrond which is very close to ICC. Gets defeated by Anduin plot armor.
10.0 - Galakrond as main villain and Dragon Isles.
Why would the Jailer go to Azeroth? If he finally gets released from his prison, he can conquer the remainder of the Shadowlands and reign supreme over all the souls of all who will ever die in the future.
Going to Azeroth where he has no power base would be immensely stupid.
Just sayin’, going to Azeroth right away would be stupid. First conquer the Shadowlands entirely, then once he’s that much more powerful make his move to Azeroth.
I think 9.2 will the Sepulcher arc. Because the Jailer is looking for the Sepulcher of the First Ones for some knowledge he wants in it. I think he’ll go there first before going to Azeroth, which that would be for 9.3 his big invasion into our world. But who knows. Anything can happen.
Then there would be no “World of Warcraft” right? I read *somewhere that they already have a team making 10.0 and 10.X.X patches, so 9.2/9.3 Jailer ruling Shadowlands and taking over Azeroth wouldn’t make any sense
9.2 - The Jailer finds it, and it is a race against time to stop him from doing something evil thing that will shake the cosmos. We defeat him, but something bad happens anyways that sets up the events to come in 10.0.
10.0 - We’ve already forgotten about the inciting incident that kicked off the expansion and are instead focusing on some new thing. Blizzard will kind of playfully mention that there will be some pay-off, but it is never mentioned again. Also, your soul-binds no longer work.
