I received my copy of Eyes of Bayonetta from Kinokuniya today. Truth be told, I'm a little disappointed with this artbook. It's paperback and comes in a cardboard sleeve. Half the space in the sleeve is taken up by a box for the DVD.
Coming in at 224 pages, inside the book itself, there's a ton of concept art for Bayonetta, but it's all pretty small. To be fair, there are probably hundreds of them. The character artwork section takes up about 1/3 of the book, and Bayonetta herself takes up about half this section.
The remaining two thirds are comprised of the enemies and items in the game. Each enemy has at best a single art piece, some have none, along with their render. All of the advertising copy appears in 2nd to last section, but non are larger than 1/4 of a page.
There are also two separate fold out posters that contain the renders of all character and enemy models in the game (the same as is shown in game after the credits).
Finally, the DVD accompanying this is region encoded. Really, enterbrain? REALLY!? This isn't a fucking movie, it's a behind the scenes DVD. Fortunately, VLC takes care of that problem easily. (Anybody interested in translating this thing by the way?)
I purchase a fair number of artbooks, and this one is about average at best. A good portion of this material can be seen in the UK-published Bayonetta Strategy Guide. It's hardcover and comes with a ribbon bookmark that matches the ones worn in Bayonetta's hair. I give this a 6.5 / 10 - and this is coming from a HUUUGE Bayonetta fan.
