Since the release of Rock Band, Harmonix have been consistently putting out downloadable content for the game week after week. Over the past five years they have managed to hit their weekly schedule of new musical content, which leads to a library now full of over 4,000 DLC tracks. It's hard to say that anyone else has ever come close with variety of content, even a certain PC train simulator.
With that said, Harmonix simply wouldn't be able to do this forever. Today they have announced the end of new DLC releases for April 2nd. Here is their thank you message to fans:
"We hope that you“ll all agree that this has been a tremendous run, and you should know it“s a ride that we at Harmonix have been thrilled to be a part of. We“re going to continue to support the forums and RockBand.com and hope to still see you rocking out online, in photos of Rock Band parties shared on Twitter and Facebook, or here on the forums. Whether you waited in line for a midnight release of Rock Band over 5 years ago, or you just joined the party with Rock Band Blitzâ€¦ whether you“ve downloaded every single song we“ve ever released, or you“ve just played on disc songs until your neighbors moved awayâ€¦ whether you“re a metal shredder, or a bubblegum pop singerâ€¦ thank you for being a part of our band."
Why are they stopping now? Harmonix has a few games they're working on the moment and none of them are a Rock Band title. Their resources simply can't be spent on keeping up with continuous updates. They have not ruled out the possibility that they may release new DLC again at some point, but for now they can't even switch to a monthly schedule. A 50% off sale on all Rock Band DLC is ongoing in case fans would like to grab some tracks from the massive library.
