The SDCC reveal of the actual toys will be in a new News topic here, but as a bit more of a tease, it looks like someone might have taken a photo of part of a banner at the Hasbro display that has the Combiner art on it... with a close up shot of the head of Victorion.

How long will it take before someone who knows Cybertronian Font, to translate what's written on the chestplate (the redeco of Groove).
