Link is not a girl. Link is also not right handed and definitely doesn't have B cup breasts.

Also, note that the character here uses a bow, even in reasonably close quarters combat. It fact, she doesn't even appear to HAVE a sword. Shield, yes. Sword, no. Legend of Zelda has a main character who's iconic weapon is a bow. Also, she tends to wear black cloaks when riding horseback at some point in most games.

It's Zelda. Trust me.

You didn't read the earlier posts, did you?  http://mmgn.com/wiiu/news--that-was-link-in-zelda-wii-u-trailer-aonuma

That proves that it not only is INDEED Link in the trailer, but also that Link is a male.
