Apparently a Chinese source of TFs KOs has pirated the Ultimate Optimus toy, and in the exclusive "Year of the Dragon" deco... which is currently being sold by Amazon.com.

The bronze parts look to be yellow (to help spot it), but just be aware of cheap listings online.

As much as I hate KOs of Transformers toys, it's KOs of limited edition figures that annoy me most... even the ones I don't have, because it spoils the urge to hunt them down, in fear of getting a fake.
