Miyamoto's "Demo Play" to hit DS

The Nintendo "Demo Play Patent

Japan's prominent news leaker Nikkei, is reporting that Shigeru Miyamoto's upcoming"Demo Play" feature to be used in some Wii software titles will also be used on the DS.

Demo Play allows novice gamers the ability to, in the middle of a challenging part, watch a demo video of how to complete it. It's unclear how it could differ from game to game, but Nikkei reports that the mode will serve as a "skip feature." Demo Play will likely make its debut with New Super Mario Bros. Wii, debuting this winter.
