It's no surprise that with the huge success of Guitar Hero: On Tour for the DS there would be a sequel.  Announced at E3 this year was Guitar Hero: On Tour Decades and IGN has released the first details on this new game.

One of the big new features is the ability to play any GH: On Tour song (including from the original and any future games) over WiFi.

Ten songs have been revealed, from the "Modern" and "2000s" sets.  Each decade will have its own themed venue.

The revealed songlist is after the break.

In a blast from the past, this week brings four songs from Devo and Duran Duran as well as one by the Janitors from the soundtrack to the upcoming movie American Mall. The two Devo tracks have been re-recorded exclusively for Rock Band. Songs and pricing after the jump.

This week brings metal to the masses with a Roadrunner Records 6-pack featuring Airbourne, DevilDriver, Dream Theater, Killswitch Engage, Machine Head, and Megadeth. These songs are available at a discount for a limited time; songs and pricing after the jump.

IGN has revealed the full achievement list (minus a couple secret achievements) for Rock Band 2.  The achievements look to be a little more varied this time around, including achievements for things such as making a band logo and using the new drum trainer.

There's no word on whether RB2 will have trophies in the PS3 version.

The full list is after the break.
