Got vol.2 of the BD and would like to comment on a couple of things 1) I'm not sure if it's me, but it seems like the subs (which are based on the CR subs) have been tidied up a lot more. 2) The extras alone should have make this vol cost a lot more.
They included the first hour of the 2013 New Years Live concert in this volume which to be honest is something unheard of. I mean I've seen shows BDs/DVDs where they include clips from concerts/events, but this extra alone goes beyond what I paid for my BD. I'll just chalk this to me buying the concert but getting the anime episodes as extras.
