I know, we haven't got to TF5 yet. That aside, and hoping that Unicron is coming in TF6, I got a sweet idea - What if most of the Transformers we know come back? Example, Ratchet can come back easily, due to his spark still being active. We seen a Shockwave drone running around. Perhaps a SoundBlaster would be cool? How about, Skywarp and Thundercracker being clones of Starscream, and Starscream returning? How about, Lazerbeak coming back, with Buzzsaw as a clone? I think it would be really cool, to see an all out war with Unicron to end a trilogy. Then, if the characters I listed above come back, they could all go their separate ways...and start a new beginning of life...literally. Then that could be another soft reboot for someone else to carry on, or they could just end the trilogy like that. Thoughts?
