I recently acquired a prototype of the Botcon 2008 Optimus Prime (it is not here yet, but I'm so excited waiting for it that I wanted to post). It looks to be a final shot piece, with the exception of the "silver-wash" paint app to the upper legs. Here are some pics. Enjoy! One other thing, are any other Botcon prototypes known to exist? This is the first and only one I have ever encountered.
