I've been considering this after people started quoting the adaptations. While yes, they will follow the movie to at least a 60 percent degree, consider the previous comics and novels. All of which included or excluded scenes. Megatron's habit of devouring sparks for instance. It seems very likely the adapatations were done long before this movie was finished, and therefore there are likely to be a number of running changes, as hinted by the new Iridescence clips. Just a thought
