Just got my copy in.
EDIT 12/16: Also, I just noticed that the paper used for printing is slightly colored to reflect the color of the cover (i.e., 1K is slightly blue, 2K is slightly red, and 3K is slightly yellow). It's a nice little detail, although at first I thought that the paper had already become discolored. Here's a comparison between a page from each of the Koume Keito doujinshi and one of the Meme50 ones:
Also, a comparison between the saitom, Meme50, and Koume Keito boxsets:
The new box is slightly larger in width and height that the Meme50 one.
