This might be discussed elsewhere but I don't know what the thread could possibly be called as I can't identify this monstrosity myself. I heard Michaele Bay didn't want to have mass shifting in this movie, but exactly what on earth is the size of this "Big wheel" thing that they have in the trailer? It's wheel is the diameter of a 6 lane highway. I was told its supposedly one of the Constructicons but unless the Constructicons are showing up as Cybertronian constructions vehicles, what the hell is that. Secondly, if mass shifting is out? (Even if we don't count the cube and frenzy's head) A transformer Meteor that big would probably level a city.
