They should release something like that when Ayu dies, not before.
As several persons already said, it's useles for those who have the first compilations of clips (A Clips, A Clips vol. II, A Complete Clip Box) AND the post-RAINBOW albums in CD+DVD edition.
I could have thought buying it if it would have been some new material (unreleased PV or alternate versions...), but as it is now, it's definitely not for me
And for that price, I can have much and much more things haha .
