I would think Starscream would be more expensive than Bee. "Saturn" is the same price point as Bee, which leads me to believe that it's probably Barricade. It was also said that Saturn is a character in the TLK toy line. If they're going by previous movies, and Saturn was in those previous movies as well as this one, it narrows it down to Barricade. He would also be the same price point as Bee, as they are both carbots.
