I loved the new trailer, it give us all possibilities where this movie will be going or could. But the downside is? say this new transformer has a big part to play in the main part of the film, and if it is unicron are we going to have to many main decepticons. It could work out that the autobots are up against it maybe this is why unicron will be in it, to give the audience the sense of the odds are against the autobots. But you look at the most powerful decepticons I say there is a top 5 of the main decepticons, how are the autobots going to compete with the decepticons. Will prime have to at times carry the burden has he is the only guy that could beat the main decepticons, especially the most dangerous villians in megatron shockwave and possibly unicron. the top 5 main decepticons megatron shockwave soundwave starscream and maybe unicron that is without the other decepticons that will also play a big part in the film. How is bay going to do a balancing act, to give all these guys enough screen time that's without the autobots and the humans. Maybe soundwave will have a similar role like in ROTF, he will stay in space even though I do hope he starts fighting not blown up when he is in space.
