Or mook, as the Japanese call it. Hot off the presses, just printed in Japan. Mainly covers the 11+, but some references to earlier models also. I bought mine from Amazon Japan at this link:

About $20 delivered, and highly recommended for serious 10 fans. Note that text is virtually all in Japanese, so buy it for the pictures.

Cheers,

How much English is there in it?

Virtually none, but lots and lots of pretty pictures.
