This week's issue of Famitsu magazine reveals that Agitha from The Legend of Zelda: Twilight Princess will be joining in on the action, and that Zant and Argorok will appear in the game in some form.
There's also another playable character named Lana, but it's unclear who this is at the moment. We'll find out more soon, and for now you can take a gander at the latest footage of Link busting up baddies with the Fire Rod if you missed it earlier.
