Just out on the Asian SNS is what is being called an image of the Transformers ROTB Scourge Studio Series Leader class figure. The heavily obscured image shows a jumble of Bayformer alien parts that do look like the screen appearence from the trailer, below. We'll have to wait until the leakers come clean to know more. If it is real, peer at the image below in the meantime.
NOTE - As always, it is not official until Hasbro or Takara announces it. So take all this as a rumor until we have the official word.
So in this step back to the Bayverse era Scourge is Tarn lol
