Apparently the images were posted to the members section of the official Transformers fanclub, so if you're of the opinion that getting news slightly earlier is worth an annual subscription you can register here.a 3", fully realized Unicron head, with mechanical tentacles on the bottom, and half his face shorn off, revealing its mechanical substructure.
It's awesome, and it'll be released with the initial wave of Primus figures later this year.
I'm not sure if Susp is being at all sarcastic with the description, but you know the drill... if anyone has/wants pics, head for a seedier website to post/see them.
Additional: the head will apparently be packed with only initial stock of the Cybertron Primus toy, probably to encourage more to buy early on rather than wait for possible clearance sales. If true, it's likely this won't be common (if actually available) outside the US.
[edit] Having just seen it... er, my recommendation would be to not bother looking for pics. Get Primus if you think it's a cool toy, but the Unicron head isn't anything special. [/edit]

Q: What's the latest on the new Cybertron Primus item for this fall? When will it be available? I heard that the US version will have something unique vs. the Japanese version- what's the scoop?
A: We can tell by the number of emails that there is great excitement for this character. The mighty creator of the Transformers race will be released this summer to all stores. You can change him from robot-mode to battle station-mode to planet-mode, and unlock cool features with the Cyber Planet Key. In addition, the INITIAL quantities will include a bonus 3-inch battle-damaged Unicron head (US only). Here's the first look at the Unicron head. Enjoy!
