Nintendo of Japan have put up an interview, speaking with Shigeru Miyamoto. In this interview he had confirmed that the next Zelda game will feature the Motionplus Accessory
Some of the interview has been translated into English.
"About MotionPlus. We're implementing it so that players can feel like they themselves are holding the sword. In the previous Zelda (Twilight Princess) the targeting was based on the IR pointer. This time however, we'll be using MotionPlus for a variety of more convenient targeting systems that will allow for more pleasant gameplay"
He also spoke of some information regarding 'Legend of Zelda: Spirit Tracks'.
"Spirit Tracks will be really fun. It's turning out to be rather challenging. Many of our Japanese customers were introduced to the Zelda series with Phantom Hourglass, and Spirit Tracks could prove to be kind of hard for them, but I thought we'd show them what Zelda is really made of this time around. So it's turning into quite a unique title"
With this information being released, Nintendo are creating more and more of a hype. By the sounds of it, the upcoming Wii Zelda will be great!
