The character doesn't look too different from other Link styles to me, so I didn't even think "Hey, wait, that's a girl..." but maybe I've been programmed to consider anyone who looks remotely like Link to be a guy. And it's kind of sad that without super obvious feminine visual cues that I'm like, nah, it's still gonna be a guy.
I want to be so wrong though.
Girllllllll embrace it. We're finally going to get a female lead in Zelda!
But yeah I like the design even more if it's a girl because it means we don't have to have an overly feminine character(not that theres anything wrong with one) to be the lead.
I really don't think the creators would risk this because I'm sure they know there would be a huge backlash if it's just Link
