Without much fanfare, Nintendo went ahead and announced Guitar Hero On Tour: Decades at their E3 2008 press conference. Later Activision confirmed it, simply saying -- more or less -- "Yup, it's a follow up to Guitar Hero: On Tour for the DS." 

Now we have some new screens, and from what we can tell, it's going to be Guitar Hero: On Tour with some new songs. Tracks confirmed so far: 

• Red Hot Chili Peppers - "Can't Stop"
• Paramore - "crushcrushcrush"
• All-American Rejects - "Dirty Little Secret"
• The Darkness - "I Believe in a Thing Called Love"
• Jimmy Eat World - "The Middle"
• Linkin Park - "One Step Closer"
• Foo Fighters - "The Pretender"
• Seether - "Remedy"
• Smashing Pumpkins - "Tarantula"
• Fall Out Boy - "The Take Over, The Break's Over"

Users of the original On Tour will be able to share songs with those that have the Decades cart as well, though we're not entirely sure how that'll work. Our first guess is usually black magic, but that was wrong when we guessed it would be used to facilitate Xbox/Xbox 360 backwards compatibility.

Guitar Hero On Tour: Decades will be available this fall and your fingers will fall off trying to play it.
