Green Day: Rock Band dated

Harmonix has staple-gunned a global release date to its upcoming music romp Green Day: Rock Band, confirming the spin-off title will be released for PS3, 360 and Wii on June 8.

The company also revealed that users will be able to export all 47 tracks from the game to any existing core Rock Band title (including Rock Band 3, due out this holiday season) for the sum of $10 USD. However, folk who pre-order the game can do it free of charge.

A special edition release is also in the pipeline, which includes the game, six free tracks worth of DLC, a swanky new packaging design as well as the track export feature.
