Is  Thor now a woman ?

Thor: Love and Thunder will be released on July 7, 2022

Chris Hemsworth as Thor 

Natalie Portman as Jane Foster /  Mighty Thor

In the comics she picks up the hammer after Thor becomes unworthy. 

For the film its hard to say, I suspect that they will blend some of the War of the Realms stuff where Mjolnir is reforged.

and Jane Foster wields an alternate Hammer that had been shattered and reformed.
