Harmonix is finished with weekly DLC for Rock Band Unplugged
Harmonix has confirmed to Joystiq that weekly DLC for Rock Band Unplugged is finished.
Apparently, it has "run through [its] planned slate" and the firm is "very pleased with the performance of the Rock Band Unplugged game on PSP, the Rock Band PSP bundle and PSPgo starter kit" which has 100 tracks through the disc and DLC combined.
Currently, the team is hard at work on the Rock Band Network, console DLC, and "unannounced future projects."
Future "event releases" are a possibility, but weekly DLC is finito.
