The thing is the CD/DVD should have already been printed/manufactured right? I don't think they will want to waste the money by printing new CD/DVD. Not sure about CD/DVD jackets/covers.
But if they do decide to reprint the CD/DVD, can you imagine the tens of thousands of the original copies going into waste? I hope they don't do that.
IMO, may as well just sell them as it is and they can just print new copies with the current line-up, I am sure hardcore J=J fans won't mind having the original versions and it would have been a nice parting gift for Sayuki's fans.
