So,recently I have been thinking about the voice in the trailer. It sort of.hit me by random - I remembered that there was information of another Prime in this movie. Now, here is where it gets interesting.Perhaps,after the near destruction of Cybertron the remaining authorities of the Teansformers came to an understanding that it is not possible to containt peace with humans and transformers on Earth.The authorities - possibly the remaining Primes or Knights,or perhaps the Council,infect the Knightship and send Lockdown to Earth. Why does Lockdown call them the Creators? Well,it was the council who named Orion the next Prime/Knight. So,in my opinion, the voice in the trailer is the voice of Solus Prime, a smith/engineer in the mythology. She is the one who,imo, inflects the spark of Prime with possibly an anti-spark,making him a shadow Prime.Perhaps,the different kind of "Decepticon" we are about to see is in fact an energy form of a Shadow Spark. What do you think?
