By the leaked info. of cyclonus. "Behind the high council on Cybertron, sits evil mastermind Cyclonus. Using his mind-controlling power, the rogue Decepticon schemes to brainwash every bot on the planet if that’s what it takes to fulfill his devious plans for Cybertron and the galaxy." That means that he may be the villain of the next season, but we know that soundwave comes back with an full Upgrade of the body. Cyclonus wants "something", and forced by that, he search every decepticon to manipulate him, and of some how he makes a portal to the dark zone, and maybe use the autobots or one to do that. He will look for soundwave and manipualte him too, and changes his body to that way to supports him with a more powerful body. AND that this time, he can talks.
