Dude, my mind is blown right now. Could it be...?!
I no longer reply to quotations beyond if you're asking a genuine question or have a non-confrontational stance.

Maybe the login screen for 10.0?

The above post should never be taken seriously in any shape or form. Failure to do so might result in laughing matters.

Ouch, 3 hours is rough. Personally I hope they can hold off an announcement until after we naturally see the 9.2 finale, so we don't learn what's happening next until we see 9.2. But, perhaps they need to announce sooner because they want to start alpha testing and other things sooner?
Right, where are all my relevant / likely leaks at? Is it Dragon Isles? PPL knew it will be Shadowlands months in advance of SL announcement, so I take it the DI thing is happening?
There was 1 shadowlands leak and it was 0% accurate outside of the name

What if the jailer was going to be successful in destroying Azeroth but Nozdormu sacrificed himself to stop it but since that isn’t his predicted death he becomes moruzond and there were other bronze dragons that were helping him and they also became infinite

Dragon Isles is very likely, it is has been a popular fan idea for several expansions now, and Blizzard actively acknowledged its existence in BfA. Like Zandalar and Kul Tiras, it represents a significant landmass, but with higher potential and creative freedom than pretty much any other landmass in the lore.
I full expect another Shadowlands situation. 10.0 will be the Dragon Isles, but every single one of the leaks we've seen so far will be completely wrong on all the details besides the most arbitrary random educated guesses (dragonflight-themed zones, maybe Night elf paladins, etc.). If there is any leak, it will be minor blurbs <1 week before the announcement, like with BfA and SL. Not any of these dumb elaborate explanations of exactly how the 9.0->10.0 transition is happening, and all the features, and a bunch of details about what happens in each zone and an explanation of exactly how the new systems work and what their rewards are.
I mean I don't know if it is Dragon Isles. Frankly there's been very little outside of those lore pointers in BFA to indicate it. Just... there isn't much shit left on Azeroth and either they were lying about a "grounded expansion" or not.
Far as stuff we know, I know our parrot friend had a rundown of stuff from Blizzard (aka datamined) that's unaccounted for. Biggest two being the HD Elwynn buildings and the Living World pointers.
