Looks like the word and pictures are out for the Dairycon 2009 Exclusive. Said to be offered as a special item, it will be available as a shared exclusive at the 2009 Dairycon, CybCon, and DutchBotcon regional Transformers events.
The images reveal an unnamed prototype of the Beast Machines Battle Unicorn done up in black and silver - black metal? The Robot image is kind of dark and looks unfinished, so its a bit hard to to tell what we are seeing for sure.

The alternate beast horse mode shows the figure with an imitation fur mane. How cool is that?

According to
Seibertron: "Sources within the organization confirmed that this was, in-fact, one of the Exclusive items being offered at this year's Dairycon."
