Gok I agree that planets should have regions but look at the link griffin supplied it shows half the planet and has "honeycomb" as far as the optics see. I doubt in a marketing pic that they would bother creating something on the other side of the planet differently but not show it - I fear this Cybertron is all "honeycomb".
I read on another board something like "Cybertron is honeycomb.. well, that explains where all the movie Bumblebees are coming from."
