Age difference: 3 years.
You've existed long enough to know which gender is getting older than the other. And as these movies continued, this seemingly small difference became a larger plot point when Michael Bay literally shoved statutory rape laws in our faces. Now, in The Last Knight, Mark Wahlberg's character Cade Yeager is getting a romantic lead who's 14 years younger.
Sure, 14 years still isn't much when you're talking about an older couple. But going by that exponential jump, the age difference in the 19th film will be 47,221,574,400 years. Failing that, I'm gonna say that Transformers 2060 will feature a love story between a 16-year-old girl and a 60-year old dude -- probably played by the kid who plays Dustin on Stranger Things. Also, 70-year-old Mark Wahlberg will totally be there, along with a wacky black sidekick friend played by Idris Elba. When asked why such a prestigious and old actor would participate in Transformers, Elba will go on about what an artistic inspiration 90-year-old Michael Bay is and that the film was a blast to make. Because that's literally what happens every time a veteran actor farts their way through the Transformers cash-tunnel.
He was doing the scare quotes in his heart.
There's no way around it: Transformers 2060 will be about 9/11.
Sorry, but it's absolutely going to happen. If the first five movies can rewrite the creation of the Hoover Dam and Pyramids, turn the moon landing into a alien spaceship hunt, kill the dinosaurs, and now reveal a plotline where the Autobots fought the Nazis... there's no reason why 40 years from now we'll learn that the Boeings which struck the World Trade Center were secretly Airwave and Skyhopper. Our heroes will discover some lost video featuring a CG-resurrected John Turturro explaining that Ground Zero was the secret crash site of an Autobot holding ship called Alchemor Prison, and September 11th was one of several Decepticon attempts at a prison break (the first being in 1993).
Technically that means these people would still be wrong.
You know this in your heart to be true. The crisis of the film will be the investigation into this long-lost secret, followed by the climax when Megatron finally manages to spring his friends from their underground jail. Sure enough, the 9/11 memorial will detonate like a disgruntled MythBuster as extras run down West Street without a single drop of historical self-awareness. Out from the smoldering hole will emerge Groundpounder, Sharkticon, and any other sucky barrel-wash 19 films have yet to digitize. We'll also see the Stunticons and most definitely begin a live action spin-off for Transformers: Kiss Players -- which was the Japanese series where robots get "power-ups" every time they're kissed by underage girls.
