One of two SDCC exclusives this year is Ultimate Optimus Prime packed in vehicle mode in a very long Alternators-like bubble package, with a metallic red cardboard sleeve over it. Prime also comes with a sticker sheet for customising the trailer.
Hope Robot Kingdom and the other Hong Kong and Asia-based toy e-tailers get them in like they did with SDCC 2010 Blaster.
