The first listing is titled "TRANSFORMERS - Platinum Edition - Optimus Prime (Year of the Horse) Figure - English Edition", priced at $139.99, and scheduled to release in December. Based on the description it seems likely this will be a reissue of the Masterpiece MP-10 Optimus Prime mold. However, the additional info mentions 2 AA batteries, which are not required for the MP-10 mold.
The second is titled as "TRA SUPREME STARSCREAM CNY PLATINUM" with a $119.99 price, but no description beyond the name. This is also scheduled for a December release.
