It's always hard to say with release dates - as noted, many factors go into a release of an album. I'm glad that the most tentative stuff is taken care of already, which is allowing me to refocus on Lufia 2 .
But yeah, a fluid thread would be no good as some releases are meant to be kept secret until they're out by director intention. The best I can give is an informal estimate based on my knowledge. I do want to see this out asap though, the wait has been too long!
