Eh to be fair, X-Corp and Children of the Atom don't seem to be getting relaunches or sequels either.
I think the Children of the Atom team might show up in Ayala's New Mutants down the line. Or Gimmick at the very least, who Ayala seems to have plans for.
As for X-Corp, given that Selene is in IXM and Monet was in the X-Men vote, I think it's done.
I agree with BobbysWorld that this will probably be (the first appearance of) a younger Earth-616 version of Brimstone Love, as opposed to the X-Men 2099 one who was from Earth-928.
That explains the minor cosmetic differences in his new design and allows Orlando the freedom to pick and choose who he wants for this new Theater of Pain.
