ESRB has been getting on top of things to keep the anti video game violence crowd calmed down which is great news, but also has the kinks to work out. ESRB new system has already leaked several things early to the gaming world including a important event in Killzone 2 storyline, a possible Final Fantasy game heading to Wii, and now Rock Band 2 track packs have found their way to the list.

In a recent listing on the ESRB site you can see that another Rock Band 2 track pack is on the way. The pack is titled “Classic Rock Pack 1” and will feature several songs that are currently available to download like other packs. Based on the lyrics listed several sites have rumored at The Steve Miller Band and The Dead Kennedys being featured with several songs. Track packs normally include 20+ songs and are meant for those that don't have access to the online store.

Further details about the upcoming track pack are still unconfirmed but maybe the ESRB should work with developers to release this info at a planned date before something even bigger gets revealed. The last thing we want is to hear Solid Snake's outcome in a future Metal Gear, if there is one.
