The only thing I'm willing to predict about what will happen when Brevoort takes over is that instead of an upper/lowercase font for the entire line, it will be more of a title-by-title thing, with some writers specially requesting mixed-case font like Ryan North on "Fantastic Four."
Everything else, I have no idea. Even the mutant status of Quicksilver, Scarlet Witch and Franklin Richards, which everyone knows was about keeping them on the Avengers/FF side of things, seems like it could go either way depending on how much Brevoort personally likes those retcons.
