Activision is announcing Backstage with Guitar Hero for Playstation Home.

Backstage with Guitar Hero will give Guitar Hero player around the globe to a themed backstage loungde and a massive concert venue where they can meet, hang out, and see the latest videos for upcoming titles on the GH franchise. Backstage with Guitar Hero will continue to evolve over time.

Sounds like this could really be cool, plus if it is still being "built", users could have a say in what they would like to see.
