My apologies if this has been answered in this thread, but: is there a definite source that details what characters and concepts that Fox has rights to? Some of the responses on this topic have been super-specific, so I'm wondering where this info has been discussed or disclosed.
I guess I should look into this Inhumans push from Marvel, and what it might mean for their regular roster of mutants; part of me even dreads getting back into all of this, as I'm sure whatever's been going on in the MU (and DC for that matter) is hopelessly convoluted. I wonder if either company would ever dare publish monthly single issue books with no concern for shared-universe continuity?
