Are they really going for the Beast Machines route of having Cybertron a techno-organic paradise? I hope to see Botanica and those iconic blue flowers from the IDW comics.
I am of the opinion that is not Cybertron for that very reason. Seems more likely to be a homebase of sorts for the Quintessons.
The greenery and the size of the planetoid suggests that it's not Cybertron. I'm in the boat saying it's the Creators' home base. The Creators were shown to be organic, remember? A techno-organic planet seems to jive with their organic nature and the fact that they made an entire robotic species.
That would be awful. I've waited ten years for a proper movie-verse Cybertron to be explored properly. I ain't having no green shit on it.
