Powermaster Ultra Prime. You can now see if the toy is worth your time and money. Also, we have our possible first image of the MP10 Ghostbusters Optimus Prime. The image seems more like something done digitally than the real thing though the real question is if it is an image from an actual source or not. The listing is from TFs-Express and they are currently asking for a 50 pound deposit. This was the first site to list the reissue of MP09 Rodimus.
UPDATE: The image below is indeed a fan made digibash used as a stand in image for a real listing
