New Guitar Hero IV controller unveiled?

The next instalment in the Guitar Hero series will work with a controller that lets you peform more impressive solos.

That's according to leaks from documents by market research Intellisponse that are flying around the Internet.

Apparently the Guitar Hero World Tour controller will feature a "new touch-sensitive guitar Neck Slide" which "opens up the entire guitar neck for unbound solos", so you can "shred how you want".

As previously announced the game will ship with a microphone and wireless drum kit, complete with cymbals and soft pads for quieter play. The whole shebang will cost USD 179.99, according to Intellisponse. Historical evidence suggests it'll be more expensive in Europe, but perhaps lessons will be learned from the Rock Band row and the mark-up won't be too high.

The tracklist is said to include songs from Jimi Hendrix, The Doors, Foo Fighters, Smashing Pumpkins, Korn, System of a Down, Ozzy Osbourne, Interpol, Muse and "dozens more".

Guitar Hero World Tour has already been confirmed for launch on PS2, PS3, Xbox 360 and Wii later this year. For more official details, check out our previous coverage.
