Deb Aoki at About.com is such a sensible person. When the Viewfinder license was announced, she shot off some questions to Michelle Mauk, Graphic Designer and Marketing Manager at DMP. In addition to answers to Deb's questions, there are also comments to fans from DMP's Editor in Chief, Fred Lui.

To boil it down, the June imprint was chosen for its wider distribution, as suspected. Also, the book will MSRP at $13.95 in B6 size, which I believe is standard takubon size. We should have volumes 1 and 2 by the end of the year. DMP will be treating this book very specially, even on the June imprint, which I believe is their address toward censorship. Also, keep an eye on the website for the series, it will have some cool stuff eventually. The license was very costly to DMP, but it was the book most fans requested from DMP, so they went for it in the name of their fans. The editor in chief asks fans to support the book.
It's a great article, so despite my synopsis, I hope you go read it for yourself and then thank Deb for providing it to us.
