Harmonix and MTV Games are at it again with a new Rock Band game, this time heading to the PSP! In Sony's "Destination PlayStation" press event, Sony announced that Rock Band Unplugged will be heading to the PSP sometime near the end of the year. Very few details have been revealed (such as the instrument interface or track listing). It has been confirmed that the PSP Store will host seperate downloadable tracks similar to the previous Rock Band ports on the consoles.

From Sony Computer Entertainment America:
"Publisher support for the PSP system will continue throughout the year with Rock Band Unplugged™, launching exclusively on PSP. MTV Games and Harmonix announced separately that gamers will be able to take Rock Band Unplugged on the road with the first ever portable version of the popular music and gaming experience. Rock Band Unplugged will take center stage as it leverages the PSP system’s Wi-Fi capabilities and becomes the first PSP game to include a fully-featured in-game store for downloadable content in the North American and Europeans markets."
