Right now Marvel is selling a new 2099 future as the "official" future of the 616. The had been any mentions to krakoa or the status of the mutants in that future yet ( probably because that would spoil the end of Hickman run, as the status of the mutants is an important plot point) If they make a new X-men 2099 series what would you like to see?

Keep in mind that in that world:

-Corporations dominate the world

- All the heroes are dead and Doom wiped the memory of the world about them.

- Its unknow if mutants exist still or not, at least still remembered as a character ask someone" if she is a mutant now"
