It looks like Transformers: The Last Knight will have a literal knight in shining armor in it, based on pics from the Staffin distrtict at the Isle of Skye, Scotland Facebook page. The left image represents the set of images which is said to be from Transformers: The Last Knight filming at the location. The other images show the knight (who reminds me of one of the Hobbits from the trilogy) and the helicopter used to film a scene. My guess is, much like the previous movies, there will be a flashback to the past for some Transformers related artifact or event that will tie into the movie's present day plot (why break the franchise's script formula if it keeps working.).
Sadly this go round Michael Bay has done a very effective job of keeping his sets locked down so have been unable to provide any real news about the movie beyond whatever pictures the production is releasing through their social media sites. This is no different as an Instagram note from the director reveals that Transformers: The Last Knight has left Detroit. Apparently he gets to have fun with some Victoria's Secret models in Paris before "Back tomorrow to Transformers in Scotland." I assume after that they will head to London for filming.
A new episode of Transformers: Combiner Wars is now available in the US. It focuses only on Optimus Prime and a very angry Windblade who attempts to kill Prime. The resulting fight is actually a nice show of Prime's effortless power and conveys with an economy of motion and words why he was the leader of the Autobots. The episode for the US can be found at go90.com. Below is the international posting of the video. It is region locked for the US and possibly other places.
