Though the title will support all previous Guitar Hero guitars, the new wireless instrument adds a touch pad below the five standard fret buttons. IGN claims the pad lets players "mimic a slap bass" and tweak sustained notes.

In all, the game is said to sport over 85 master tracks, but will not be compatible the existing downloadable content for Guitar Hero 3. Rival Harmonix has stated its desire to make future entries in the competing Rock Band series compatible with all RB DLC.

Thus far, bands and tracks confirmed to appear in Guitar Hero World Tour are:

• Sublime - "Santeria"
• Billy Idol - "Rebel Yell"
• Foo Fighters - "Everlong"
• Linkin Park
• Van Halen
• The Eagles

The touch-sensitive guitar was first unveiled in a leak of marketing materials earlier this week. While those materials further detailed a $180 price point and a number of bands, the only other Activision-confirmed tidbit was that the Foo Fighters will be involved.

Meanwhile, the following artists and tracks are believed to be included due to leaks, Activision-issued media, or record label announcements.

• At the Drive-In - "One Armed Scissor
• Def Leppard
• Aerosmith
• Jimi Hendrix
• The Doors
• Smashing Pumpkins
• KoRn
• System of a Down
• Ozzy Osbourne
• Interpol
• Muse
• The Police
• Blink 182
• Red Hot Chili Peppers

Commonly known as Guitar Hero IV, World Tour adds drums and vocal support to the mix, along with a focus on music creation. It is not yet known if the instruments of World Tour will be cross-compatible with Harmonix's Rock Band and Zoe Mode's Rock Revolution or vice versa.

As with Guitar Hero 3 and Aerosmith, Neversoft is developing the PS3 and 360 editions of Guitar Hero World Tour, with Vicarious Visions on the Wii edition and Budcat handling the PS2 iteration.
