Probably no more Rock Band PSP DLC
"Planned slate" is now finished.
MTV Games has said that it has "run through our planned slate of Rock Band Unplugged DLC", meaning there probably won't be any more.
The very enjoyable PSP spin-off to the main Rock Band series has around 100 tracks available across the UMD disc and associated DLC shop.
"Right now, our DLC team is focused on Rock Band Network, weekly console DLC, and unannounced future projects," MTV told GameSpot.
Rock Band Unplugged, developed by Backbone Entertainment and Harmonix, translates the plastic-instrument gameplay of the home console series to Sony's portable by taking a step back towards the genre's origins - and specifically games like FreQuency and Amplitude.
