Possibility of Another Symphony CD
Nintendo World Report recently had an interview with Jeron Moore, the creative producer of Symphony of the Goddesses. Some interesting points were brought up; towards the end it was hinted that another CD containing what was not released with Skyward Sword's Symphony CD will be on it.
NWR: I did have one special request to ask you. At the end of this tour, will you release a new CD with all the new content that wasn't on the Skyward Sword disc?
JM: All I can say is… that's something that we're working on at this time. Because the disc with Skyward Sword has been so close to release, Nintendo doesn't want to move forward quite yet. But send them your request; I think they listen. So you bug them enough, maybe there will be something. I would love to do that.
