Here's one from a Baidu message board that we weren't expecting. "Throne of The Primes" appears to be Power of The Primes Optimal Optimus in a black and white color scheme based on Optimus Primal's original colors, packaged seated on a cardboard "throne" and featuring a new scepter accessory and what very much looks like a crown. Less obvious is what might be part of a ring of golden Prime Masters behind the throne, lending to the "Throne of The Primes" title. While no markings are shown to indicate convention exclusivity, the unique accessories and possible numerous packed in extra Prime Masters certainly lend to the idea of this being an SDCC offering. If so, we're glad the exclusive with the Japanese G1 dinocassettes got to be revealed officially before the leak engine caught up this year. See the (sadly not great quality) photo below!
