I think everyone who knows intel about the game probably signed an NDA of some sorts...which implies that they'd be A LOT more careful about even slightly revealing the game. Also, the picture of the robot(at least the one in the beginning-I only skimmed through the video) looks to be a photograph with effects over it. It could easily have been some internal team, "let's make up a game and practice designing".
And, the red robot used in the Robot Builder program looks to be from the Rebound Rumble animation.
