As for how plausible this is...
On the one hand, the name is wrong and the part about Shadowlands' ending wasn't particularly accurate. Plenty of "stay a while and listen" scenes that talk about the future of particular characters and factions, and the Jailer did try to take Azeroth's soul, but there's nothing about it rupturing her and Magni never even came up. On the other hand, there's the pre-event:
This is surprisingly plausible after the Season 4 announcement. The Timewalking event it describes could easily fit into that format- after Season 4, one more short season that swaps out the Mythic+ dungeons and Shadowlands raids with a bunch of stuff on Azeroth for a month or two leading up to release. And those kinds of shakeups would have been unbelievable just a few weeks ago.
I'd still call this incredibly unlikely, but there might be some slim chance.
