And since there's always a good message to every bad message: The book is called NARUTO-ナルト-オフィシャルファンブック 秘伝・陣の書 on amazon, while the usual name would be NARUTO秘伝・陣の書オフィシャルプレミアムファンBOOK. It also has 392 pages, more then any other data/fanbook. Both facts together could mean that the amazon title is only temporary and we actually get a full databook.

For now, this is only speculation, though.
