Transformers Animated was the back up plan if the first movie flopped. Maybe we'd have season five instead of TF:Prime. Generations and Animated and War for Cybertron toys would be on the shelf and Bumblebee could still speak.
And I believe Ninja Turtles is only on hold because of budget issues not forever cancelled. I wonder of the Turtles in Time costumes are still available? Or the ones from the TV series with Venus De Milo?
