Harmonix made it official today that ongoing DLC support for Rock Band 3 will cease on April 2nd of this year. This will end the longest continous DLC support for a franchise in history, as Harmonix managed 275 consecutive weeks of releases with over 4,000 songs across all versions of Rock Band. Harmonix promised that over the next few weeks, they will be releasing several more Pro Guitar upgrades, the remaining Rock Band Blitz tracks and a few more artists appearing for the very first time. Oh, and the giant DLC sale? Harmonix will still be supporting it, so if you have some time, feel free to peruse this giant list of sale items. There you have it folks, the end of an era. Thanks to all the members of the community that alerted us to this tragic, heartbreaking news.
