The controversial "Demo Play" feature devised by Shigeru Miyamoto and Nintendo won't just be limited to New Super Mario Bros. Wii and other console-based adventures. A blurb in Japan's Nikkei newspaper notes that the feature, which allows players to skip difficult areas and watch them played automatically, will also be used in portable games in the future. Nikkei referred to it as a "skip functionality" or "skip feature."
Nikkei notes that this feature is designed for "high-speed action games," so presumably you won't be able to let Dr. Kawashima step in and count the number of people who just ran out of the house (we hate that one), nor will you be able to make the Pokémon start choosing themselves mid-battle.
