Yes, I know it already is sci-fi. But up to this point it's really only been space robots in an otherwise ordinary world. What I mean is something similar to the third season or Animated. Think Minority Report and iRobot. With the death of Decepticons, Earth advances using Autobot technology, and perhaps the Autobots themselves FINALLY get a chance to repair themselves and even get some much needed plating. That allows an excuse to redesign them somewhat and thusly make distinctly new toys. The core of all this would be a corporation who contracted with the Autobots and - naturally - turns out to be evil. Maybe even have the Autobots complacent and lazy since adapting to future Earth culture.
