"[We're going to] take Thor literally to other worlds," Feige told EW, "...[It will] primarily be the journey of that character, of he and Jane Foster and how the new dynamic with his father is working out, as well as what are the broader stakes for The Nine Worlds.”
Pretty much confirms Jane Foster is returning.
