I looked into June's web-page and it says that viewfinder 4 was already released on July 23rd...
but on Amazon UK says that it will be published on January 2012 o.O
I'v also asked about it to Bookdeposity (since I pre-orded with them), and they said the same thing.
so now I'm confused @.@
was it or was it not published already?
now they are putting on preorder vol 5 for December @.@
how can vol 5 come after vol4... @.@
clarification pls :3
