Shigeru Miyamoto disclosed to Japan's Nintendo Dream publication that instead of pushing the B button on the Wiimote for a sword swing in Legend of Zelda: Twilight Princess, the player will now control that movement with the motion of his or her arm. IGN says during E3 that Nintendo said players would get tired having to actually swing the controller, but now Miyamoto has changed his tune: "Upon actually playing it, it's more interesting this way."
There have also been changes to how the bow and arrow controls will work. At E3, you had to aim with the Wiimote and then shoot using the D pad. Now that the B button is freed, thanks to a sword overhaul, the B button will now release the arrow. Miyamoto said shooting with the D pad was too difficult. He also hinted that the Zelda at E3 was "just the tip of the nail."
According to IGN, Miyamoto also told Nintendo Dream that Nintendo may remake existing GameCube titles and add full Wiimote support. "The machine is based on GC," said Miyamoto. "We'll be upgrading the development tools, but GameCube code can be used for the most part as is. In that sense, I believe that it would be good to remake GameCube games for Wii, and that some titles would become better with the change to the Wii remote controller."
Miyamoto said these revamped GameCube titles would be sold at a lower price than normal Wii games.
