I just bought the limited edition at Tower Records. I have to say the artwork for the cover is pretty nice! You basically have to destroy the barrier tape to open the CD. After doing that the cover looks lile the other one, just in red and with four holes, through which you can see one eye of every member.
The footage you can download is cool too. There is one video from the concert of the 6.9. this year. Tatsuro, Miya and Yukke were fooling poor Satochi, by playing a new song during the encore Yukke just wrote the evening before, but Satochi didn't know of yet. It was very funny to watch how the poor guy asked the staff which song it was the three others were starting to play and the staff kept replying "Terrace", which seemed to confuse him even more.
The bonus track, that can be found on the single, is the live recording of this song amd if you look on the inside of the OBI of the single, there is a picture of a terrace and the lyrics are also written there.
Also there are a lot of photos from the two Tokyo shows at Zepp this year, as well as short clips of the wall collapsing from the first date. Since I went to both shows, having those photos and clips is a nice memory.
