4. Will the Rock Band Network continue to release content on a regular basis?
The current plan is for Harmonix to continue to support the backend technology that powers Rock Band Network on the Xbox 360 for the foreseeable future. Users on the Xbox 360 should be able to submit new content, test, and release as they have been for the last 3 years. It's important to note that this architecture relies on other technologies not directly in Harmonix's control, including the XNA architecture for submission. In the event that our ability to keep RBN up and running changes, we'll make sure to let everyone in the Creators community know with as much lead time as possible.
Unfortunately, PS3 submissions for RBN tracks are submitted in the same manner as standard Harmonix-released DLC and require constant Harmonix production attention. As a result, the last PS3 RBN release planned on our schedule is on April 2nd.
