From the complete article:
"In an interview with IGN, RedOctane's co-founder and president Kai Huang has confirmed that the Wii version of Guitar Hero III uses a guitar peripheral and has online elements.
Guitar Hero III is scheduled to hit PlayStation 2, Xbox 360, PlayStation 3 and Wii in Autumn this year. However, many were left wondering whether
the Wii version would require a guitar peripheral - like previous Guitar Hero titles - or utilise the console's Wiimote.
While the development team is still exploring innovative ways to use the remote, Kai Huang told us: "We are really excited about the Wii game because there are so many options for the Wii remote. However, you will play the game with a guitar peripheral and it will be similar to a guitar you've seen in the past."
He also confirmed that Guitar Hero III on Wii contains features included in other versions of the upcoming game - such as online play and downloadable music.
