Click here to see a video tour of High Moon Studios-- The creators of War for Cyberton and Dark of the Moon: The Game. Around 1:15, they take you to the concept art room, where you can see concept art for Wheeljack and what looks to be Sunstreaker. These two characters could be featured in the upcoming game, Transformers: Fall of Cybertron. Make sure to take a look at the tour. It's pretty cool to see the behind the scenes of a video game creation.
