Ah, false. Sony can ONLY use spiderman associated franchises. And Skrulls can only be used by Fox. Kree only by Disney/Marvel. And Scarlett Witch and Quicksilver can only be used by Disney/Marvel if they don't call them mutants (hence the "Age of Miracles"), mention Magneto, or mention the X-men or anything else related to them. And the live action TV rights are unclear but I think they currently lie with the companies that have the movie rights. At least Fox is sure that they hold the TV rights to X-men and F4.
