While we’re not sure exactly what the Transformers line is about, it is clearly somebody coming to terms with the idea that something they didn’t really believe is actually true, the same that is happening at the same moment in Star Wars: The Force Awakens.
The line is so close to identical in the trailers that it really feels like Transformers is making a Star Wars reference here, though the fact that the line isn’t perfect leaves the idea open for alternatives.
The fact that this random, out of context, line is in a trailer at all makes it seem like they want us to notice it, and without any idea what’s being referred to, all we’re thinking about is how it sounds like Star Wars.
