doesnt matter, they dont own the right to the concept of mechanized battle robot's or armor/suits, this concept was around long before that game was even conceived, it has been used in many other games, shows, movies and other forms of media.
The whole concept of them even being able to sue over it is stupid and wont happen.
To me that looks as much as a nova cat as it does optimus prime, just another big robot with guns.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
