All New DLC Will Work Exclusively on Rock Band 3 Going Forward
The same week that Activision announces DJ Hero 1 DLC is now compatible with the sequel, Harmonix has revealed that all future Rock Band DLC will only work with Rock Band 3, due to technical issues.
Although this could be considered a big deal if fans and press really wanted to make something out of nothing, Rock Band 1 and 2 had a very good run, with more post-release support than most MMOs see. The advancements in Rock Band 3 require this change, and frugal nubs not willing to pay the admission for the best rhythm music game to date will just have to deal with the 2,000+ songs currently available to them.
