The description for the upcoming episode "Regeneration" explicitly says that the Autobots and Decepticons will return to Cybertron to fight over the Omega Lock. However, the Autobots don't seem to have any means of getting there at the moment. It's not like they can hijack the Decepticon space bridge again, since it's in orbit around the moon. Wheeljack's ship could probably make it there, but it only has room for two. In spite of this, Bulkhead and Arcee were talking about "packing their bags" as if it was a sure thing! Will the Omega Keys open up a space bridge once they're all brought together?
