Form of Ready Player One Sequel?

I've just finished a re-read of "Ready Player One"; and I heard tell that Ernie had embarked on writing a sequel... Now before you all start I make the distinction between the film and the book, we are talking about the book.

In fact, those of you who haven't read the book... (Spoiler alert)... It starts out being written as the true story, to set the record straight... Straight up calling the movie out as wrong!  Oh yeah, love that preemptive strike on the Spielberg saga.

Anyway, the sequel eh?... Lets gather around the camp fire and think about this...

It can't be another hunt, we've had a hunt, Z is the man now, we may get a little friction between the members of the high-5 and Z maybe?... But it's going to be about what they find within the folds of the fabric of the Oasis.

Perhaps whether Halliday's Avatar was some form of personality transplant from his real-world body into the Oasis, some form of literal Ghost in the Machine?

I'd like to see some form of digital court, like a war-crimes tribunal, all accounts whom were Sixers being required to justify their existence?  Maybe some form of play on "The Odessa Files" in digital form, with IOI has the continuing evil?

Maybe there's some form of massive community lash back, everyone died on the release of the Cataclysm, Z resurrected the High-5 members, but everyone else was perma-death?
