Thor is a woman now.
At least he is until the next Thor movie or Age of Ultron comes out.
Let’s just remember, it’s not the first time Marvel has tried to change his gender. Look for Alex Ross’ take on the character in Earth X. I never read Earth X, so I don’t know if this idea went much further than his sketchbook.
Also, don’t forget it’s not the first time someone else became Thor. I seem to recall throughout most of the 1990s, there was a character who was Thor, but not Thor, who later became Thunderstrike when Thor became Thor again. Thor.
I think it’s cool that Marvel is trying to make one of their more popular characters a woman, but wouldn’t it be a little more meaningful if they actually created an interesting new character that doesn’t need the name of an existing property, and had their marketing department give the character a real push?
