Continuing the assault of leaked information from research firm Intellisponse and NeoGAF's rehosting of its internal documents is word that Guitar Hero World Tour, more commonly known as Guitar Hero 4, will sell in a three-instrument bundle for $180.

In addition to the previously-revealed drum kit, the PS2, PS3, 360 and Wii-bound bundle is said to contain a new guitar, featuring "a touch-sensitive guitar Neck Slide [that] opens up the entire guitar neck for unbound solos," and a microphone.

A number of bands were listed in the documents as well, including Jimi Hendrix, The Doors, Foo Fighters, Smashing Pumpkins, KoRn, System of a Down, Ozzy Osbourne, Interpol, Muse, along with a tease of "dozens more".

Competing title Rock Band, which emerged from Guitar Hero creator Harmonix last fall, is sold in a $170 three-instrument bundle on 360 and PS3.

Please keep in mind that this information is unconfirmed, and as Intellisponse is a marketing research firm, could very represent market surveys instead of actual facts.
