Our friends over at Action-HQ
have posted a listing on their website that the the Hasbro version of the much anticipated Masterpiece Convoy will be made up mostly of plastics rather than die-cast metal. If this turns out to be true, Optimus Prime joins the Alternators in what fans have dubbed the "Transformers that should have been awesome but Hasbro ****ed ´em up" category of high-end figures. Keep in mind that this has yet to be 100% confirmed.
