At its annual retail and publisher conference Destination PlayStation, Sony announced its unprecedented line up for its PlayStation Portable system.
One of the most exciting news is that MTV Games and Harmonix have finally announced that they're working on the first handheld version of the hit band game.
"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."
"Rock Band Unplugged" will be released exclusively on PSP and is due out in fall 2009.
