I don’t even understand what they are trying to say.
Are they saying Thor is now a woman? Or that there is also a woman version of Thor? Both still exist? Kind of like supergirl with superman.
I think there is a male and female version and both will appear in the movie.
5 years ago she was worthy in the comics he was not .
But Jane had cancer and chemo benefits were lost as Thor.
but recent comics event War of the Realms fixed things,
No idea how movies will work.

I think they are trying to say that a woman can be Thor.
Just like a woman can be a Ghostbuster. And a woman can be 007. And a woman can be a Jedi. etc, etc, etc....
