MTV expects Rock Band to activate overdrive this year and have over 5,000 songs available for play, reports Billboard. Developer Harmonix hit its goal of having over 500 songs, spread across discs and DLC, on the music platform by the end of last year.
Although we have no reason to doubt Harmonix's ability to provide content, the math dictates that an average of over 90 songs would need to release every week for the rest of 2009. Even if that figure is mitigated by special discs (like AC/DC) or Rock Band 3 (unlikely), the developer has its work cut out. We've contacted Harmonix to find out if its publisher is being realistic.
