I'm pretty sure both games are going to have new Links. There are no plot arcs left open in the Zelda series, or Zelda games needing sequels or spiritual successors. With Skyward Sword, a prequel gaming wrapping up a lot of origin stories, and the timeline coming out to wrap up all loose ends with existing Zelda canon, and also with two brand new consoles... I'm pretty sure that whatever we get on both consoles is going to be completely new.
Yeah kind of.Wow, I think I just defeated my own opinion. XD
