It was previously rumored that the new instrument addition to Guitar Hero World Tour would be the keyboard, though that doesn’t appear to be the case anymore, as project director Brian Bright shot it down in a Joystiq interview.

He noted that the keyboard controller “deserves to be introduced with its own game” and that it is something they are talking about.

The new instrument is confirmed to be something that will be used in the upcoming game’s music creation mode.

Guitar Hero World Tour is set for release this fall on PS2, PS3, Xbox 360 and Wii.
