Anyone who thinks we will have a female Thor in the comics when Avengers 2 comes out hasn't read comics-particularly Marvel Comics-for years. Marvel's been doing status quo changes with their characters that revert when a movie is about to come out for years, going back to when they "killed" Captain America and replaced him with Bucky, only to bring him back around the time the first Cap movie came back. Anyone remember how Doctor Octopus had taken over Spider-Man's body and Peter Parker was really, truly, welp yes he's dead only to revert to the status quo when Amazing Spider-Man 2 came out?
This and Sam Wilson becoming Cap is business as usual for comics. And they wonder why people who watch the movies don't flock to the comics. It's because the comics are frigging unrecognizable to them.
