The Tribute 2007 Leader Optimus toy has been listed on Robotkingdom, for a hefty price of US$90 (the 2007 version was US$50), with a release date of July 13th, which is only a week away.
The Tribute 2-pack Optimus set has just been released in Taiwan, so these are coming out fast, considering the Movie toyline is still the primary focus of Hasbro to the retailers.
