Hasbro have updated their site with many new pictures of the toys including some interesting bio of some of the characters. Here is the most interesting about Shockwave. "Cruelly efficient and unfeelingly logical, Shockwave came to Earth in search of the AllSpark shortly after Megatron. His cold devotion to logic and his peerless intellect, combined with his raw physical strength, make him one of the few Decepticons that can truly be called Megatron's rival. After decades of imprisonment underneath Chernobyl, Shockwave has begun to stir, awaiting his chance to escape his prison and avenge himself on his captors, his rivals and his enemies alike." Transformers Characters and Bios | Enter Vector Sigma: The Cybertronian Robot Database Remember the Laserbeak scene from the trailer? It definitely takes place at Pripyat (the ghost city which was mostly affected by the Chernobyl disaster). Here is a picture of Pripyat (Chernobyl) with it's abandoned Ferry Wheels So this means that Laserbeak (and maybe Soundwave) are searching for Shockwave at Chernobyl and we know that Ironhide, Prime and Lenox have a side mission in Ukraine so maybe they'll all meet there in a classic battle scene. Just to add something. Remember that Shockwave crash landed in Tunguska in 1908 in the prequel comics. I guess after that they moved him to Chernobyl.
