DVDBasen doesn't show anything yet for that item. I'm surprised Anthony over at DVDToons hasn't gotten one up yet, honestly. Believe me, I'll be talking plently about this once it hits and I have my own copy...between me and my boy, it won't ever get out of the player!
Rhino doesn't really send out review copies so you won't see any early reviews of their titles. Reviews will take awhile since the site will have to purchase the title and then review it (which we all know takes time).
