Just found an image of the DVD cover on the CDJapan site. I ordered it myself a couple of days ago, can't wait to get it.
Edit: Just got my shipping notice for my copy today, hoping it arrives soon.
Edit 2: It arrived less than an hour ago, only 4 days from Japan to the UK, not bad. Case is the same style as for the 6th Live DVD. Had a look to see what extra's there were.
Disk 1- Usual pre-show footage.
Extras- Go East!!! Go West!!!, Dance by Asahi, Ai-Chan and Ruka-Chan and Beta na Shitsuren.
Disk 2- Pre and Post show footage.
Got the card I wanted as well, 1st Gen + Suu-Chan
