The reason I think the Earick book didn't cause that much of a stir was because the book contained a collection of "moves/sleights" after all. Many of the sleights/moves taught in the book can be duplicated with other easier sleights in a cardman's eyes. This said, it is obvious that not a lot of people cared for the "new" ways to accomplish the same things (ie: 101 ways of Triumph etc), but rather for something entirely new.
Five Times Five Japan and New Magic of Japan fit the bill perfectly. This also teaches us that magicians nowadays are more interested in new "plots" as opposed to numerous ways of accomplishing an apparantly similar card control.
By the way, Mr. Kaufman, can you tell us more about the new book!? I am VERY interested!
