I doubt my site had anything to do with it, but who cares! It's FINALLY done right! Not only is the video properly interlaced (60 fields per second), it's also anamorphic widescreen!
And Nana-chan sure puts out an amazing live! I own a bunch of live DVDs, but nothing even comes close to Nana-chan's concerts, especially this one. It's a matter of scale. Nana-chan's concerts are in a class of its own.
Limited edition comes in a "birthday box" and the DVDs are contained in a booklet case (triple pack). I don't think there're any other differences, meaning you get all three DVDs even if you buy the regular edition, so if you can't find a limited edition, don't fret.
By the way, interlaced-ness (thumbs up!) makes it really hard for me to grab usable screen captures, but I am _not_ complaining. Also, I couldn't get good screencaps of all the dancers, so I've postponed putting up their pictures to disc 2 or 3 listing.
White highlight on Nana-chan's hair makes her look old, so I'm not fond of it. By the way, both Marie (left) and Mika (right) should be familiar to fans of Nana-chan concerts.
