This year's Ace Race disc, from what I have read, is NOT the new Discraft Crank. The Crank was "pre-released" at Am Worlds in ESP plastic with just a Discraft bar stamp on it. The market release is due in September.
The Ace Race disc is still a prototype and not PDGA approved yet. What better way for Discraft to have people test their prototype molds by having you buy them before they are even in production! They are typically PDGA approved a few months after all the Ace Races are over.
