It turns out that Transformers: Robots in Disguise cartoon was not cancelled. Renewed for season three, it will get an updated title of "Transformers: Robots in Disguise Combiner Force". The official synopsis:
“In the Transformers: Robots in Disguise animated series, Bumblebee and his team of Autobots — Grimlock, Strongarm, Sideswipe, Autobot Drift, and Fixit — have figured out how to work together. They’ve captured escaped Decepticon prisoners, defeated longstanding enemies, and defended our planet without any humans (other than their close allies Denny and Russell) knowing they’re here.In addition they showed off some upcoming Titans Return toys along with the tease of Trypticon's leg (below) during their panel. The scale suggests he will be Fortress Maximus/Metroplex scale. Other Titan toys include Legends Brawn, Triggerhappy, Percepter, Broadside, and more. You can find official pics here and here along with a look six-changer Sixshot (below). A large gallery of their display is at TFormers. It wasn't clear if these toys are hitting by Christmas time or next year. Considering I have yet to see any Titans Return on shelves in my area, it seems more likely they are for next year.
In the upcoming third season of the hit series, their ability to work together will be put to the ultimate test! The team faces a new Decepticon threat that is literally the biggest one they’ve faced: a team of five Decepticons who can combine to form a giant super robot and pulverize anything that stands in their way. The Decepticon Combiner team is set to wreak havoc on Earth, and it’s up to Bumblebee and the Autobots to stop them!
The team will discover that they, too, are more than meets the eye. The Decepticons aren’t the only ones who can combine into different bigger, more powerful forms! As sinister new forces rise in the galaxy and powerful enemies unite to bring down the Autobots once and for all, the team must not only learn how to fight when combined with one another, but to truly work as one. All their training…every captured Decepticon…every hard-fought battle…has as all been leading up to this. To emerge victorious, Bumblebee and the Autobots must become…a COMBINER FORCE!”
