So from the trailers the humans made Transformers from the cons that died in Chicago but what the government heads that decided to turn on the Autobots didn't know is that the ones in Chicago were the grunts, mid tech weapons, and the low tech ships, and up until then they and the bots were dealing with Cons that were traveling with little to no necessities and mid level grunts to 2 high level cons with some necessities. They also didn't think the cons would bother them after everything not realizing its not the autobots bringing them to earth but Megatron and what they now encounter are high level cons with high tech stuff with high tech ships (basically with necessities) and they will learn they don't know nothing and that their tech is as usless as scrap because I am sure word would have spread through the con ranks about the sabot rounds and other stuff and found a way around it.
As for Ratchet possibly dieing the mech who is green and shot down in the scene by the soldies could be the wrecker Roadbuster, if not then maybe Ratchet managed to fake his death because in a earlier pic that shows Optimus leading a team there is behind him a red and white ambulance.www.tfw2005.com/transformers-n…
This looks to be an interesting movie, and I can't wait to see it including the segment were Optimus hits Grimlock.
