Update April 2012: Review for Kim Jung-Gi 2007 & 2011 Collection
Update 28 Feb 2012: Looks like the book is only going to be sold through the author/publisher's website only.
Here's the 2011 sketchbook of Korean artist Kim Jung-Gi. It's a 686-page hardcover with two different covers you can choose from. There's also a limited edition.
The book contains lots of detail sketches and the art is fantastic!
You can either purchase the book on Taobao, or email his writer assistant firstname.lastname@example.org.
The book is listed at USD$60 equivalent but I'm not sure if it includes shipping. Shipping looks likely to be quite expensive because the book's thick and heavy (3.3kg). You can purchase with PayPal.
Anyway, just email David if you have questions.
Update 13 Nov 2011: Found out from DrBlack (another art book blogger) that there are pirated copies of the book floating around. So don't buy from mysterious sources. There are tips on how you can spot the original editions from the links above.
