Transformers 3 Cheat Sheet

A new cheat sheet (so spoiler warning) for Transformers 3 as information comes in. I have tagged items based on validity of the information. Rumor means the info comes second hand or through unofficial sources. Unverified means it comes from credible sources or seems likely. Verified means it was either provided from people with the movie or through mainstream media sources that are unlikely to be lied too (but no guarantees). The below is ultimately speculation until officially confirmed through those with the production.
