From reading the Million Publishing Twitter page it seems that the company is still deciding on who to use as their book exclusive figure for the upcoming Transformers Generation 2010 book. This morning they blogged that their first recommendation was to produce two exclusives for the book a gold and a silver Rodimus. The toy, I assume, would use the Henkei (Classics) mold and would be based on the Super-Link figures (Gold SuperLink Rodimus, Silver Superlink Rodimus). Though personally speaking I would rather they did a chromed Masterpiece Rodimus as other than looking nicer it would be a homage to the Primus figure they did as well as being harder for knock-offs to be made.
As my brother Moonbug pointed out, the toy could well use the Animated Rodimus mold, which would be a safer choice, but I'd still like to see a Masterpiece used.
