In a post on the company’s official forums, Harmonix developer hmxsean confirmed that Rock Band DLC will hit the Xbox Live Marketplace next week. While specifics weren’t given, hmxsean did say that we can expect an official announcement on the DLC either today or Monday at the latest. Oh, and PS3 owners won’t get the content until after next week.

There will be DLC next week. An announcement will go out today or Monday.

Sony’s offices are closed next week and the DLC will be postponed for a week until they come back (but they’ll be back on schedule the following week when they get a double-dose of DLC awesomeness). It will go up in the Xbox Marketplace as regularly scheduled.

Anything to announce? Anything at all? [Rock Band]
