I predict that they will reach some sort of agreement out of court and then we'll hear no more about it.
As an aside, I think it is kind of sad that the WT would waste their time and resources to prevent one of their songs from being recorded and distributed, especially when the artist was doing it in a positive way. I know it is part of their doctrine and belief system to be 'separate' and all that, but this issue just underscores how stupid that belief system is.
