Just out on the SNS is news and images from the cancelled Transformers game that was code named "Project Goliath". The concept art images developted by Skydance Interactive show a mixture of G1 of Bayverse inspired designs. As we can see, they put a lot of thought into the Optimus Prime design with references to the G1 cartoon and his many variants since then.
What's very interesting is how much the alternate mode looks like the 40th Anniversary Retro Optimus Prime. Hard to tell if this is was on purpose, a coincidence, or just more G1.
Additionally, there are views of a Bumblebee design that is clearly from the Rise Of The Beasts model with the dune buggy alternate mode.
Also some design work they did on an Exo-Suit model, that gives us more reason to believe this game was probably intended to follow the Paramount film, but was cancelled for unknown reasons. Check out the update and images by artist Adam Hartley of hartelstudio, thanks to @arun09345
