Guitar Hero World Tour (also known as Guitar Hero 4 or Guitar Hero IV) is the upcoming sequel to the music video game Guitar Hero series, and will be developed by Neversoft and published by RedOctane and Activision, targeted for initial October 27, 2008 release. The game is expected to be available for the Xbox 360, PlayStation 2, PlayStation 3, and Wii consoles.

While the game will continue to feature the use of a guitar-shaped controller to simulate the playing of rock music, Guitar Hero World Tour will expand to also include the use of drum and vocal peripherals, much like Rock Band.  Furthermore, the game will allow users to create custom songs from those shipped with the game, altering everything but the lyrics, and may also be able to upload and share other songs with other users.

The Guitar Hero World Tour Band Kit is available now for pre-order at Amazon for $189.99.  Amazon does not charge until it ships, and if the price drops prior to shipping, you are guaranteed the lowest price.
