The DVD on this "album" is so lacking its not even funny. Only two of the songs get a PV and only one of them gets a making of? Disappointment.
Also, I would still get it considering that this is an album and the tracks won't be released again, but I get the feeling that the last of these releases is going to be A BEST OF THE PAST 4 RELEASES.
As of right now, I'm on the fence. If the CD+DVD versions aren't limited, I might wait until the very end and then buy them all at once
