So for a song to be ported to the PS3, Harmonix first has to propose that to the artist at some point and then the artist has to accept? Why not just include the PS3 (and Wii in case support for that console comes further down the road in some form) opt-in paperwork as a basic requirement for submitting songs to the RBN? That way the only thing holding back songs from coming to the PS3 would be Harmonix's discretion, and complications resulting from not being able to contact an artist (or an artist not willing to bring them to other consoles) would be avoided.The option to bring a song over to the PS3 version of the Store will be offered at Harmonix's discretion, and even then it will be entirely "opt in." Artists will have to do some paperwork to properly port their songs onto the PlayStation Network, a process Harmonix believes no one will refuse. "It's more revenue, right?"
Anyway, happy to see that the RBN store interface is at least coming to the PS3, although it's seemingly assured that parity will never be achieved between consoles for the RBN. Unless Sony is worried about all the space for hosting the content, I don't see a reason not to try to port everything. Then you'd be making as much money as possible and not leaving certain songs as console specific.
