Marketed as a reissue of Powermaster Optimus Prime, this Toys R Us-exclusive Commemorative Series figure is in truth based on the Ginrai tooling on the toy that had previously been exclusive to Japan. It features a die-cast metal cab with translucent blue windows, and shortened, chrome smokestacks, and comes packaged with the drone Apex Bomber (formerly Ginrai's partner Godbomber), who splits into several components and combines with Prime to form "Apex Armor". As with all other Commemorative Series figures, Prime's new spring-loaded missile launcher featured an elongated missile.
So you basically get all the better aspects of Ginrai, but Hasbro safety missiles. Looks like the regular trailer also has the slide out fists that PM Prime didn't have.

RK is selling the same toy, their photo just has the front book opening open to show the toy underneath.
