Well, relaying more info here (source, op2, last.fm):
"The amazon.jp listing for LiVE credits Reliance MediaWorks as the company that is handling the Shiina Ringo releases. These are the same guys that handled the HD releases of Fantasia, the Star Wars trilogy and more. Seems like they know their stuff (

Cool bananas.
Edit: Also, works out CHEAPEST with Amazon I figured. Even with their expensive shipping. They have it currently listed for 5,117 yen less than list price, I doubt it will get cheaper than that!
