Rock Band Network 2 out on February 15th.
According to a blog post posted on the RBN creator’s site, Harmonix has announced that you can start submitting RBN 2 stuff on February 15th. It also states that RBN 2 will only be compatible with Rock Band 3. I assume this has something to do with how the songs are coded now (it’s why new Rock Band DLC is only compatible with RB3.) I have a feeling we’ll get a ton of RBN 1.0 songs pushed through in the next few weeks to facilitate RBN 2 songs.
