One announcement at SDCC is that there will be some sort of animation being done for Combiner Wars by a company called Machinima... but it is rather vague as to what format it will take, or how/where it will be broadcast. (and the details of what the company does was rather confusing, as they seem to do a wide variety of things)

“The Transformers are coming to Machinima.
Hasbro, the toy company-now-play brand, has partnered with the online gamer and video platform to produce a new animated series based on its Transformers: Combiner Wars line.
Combiner Wars is a storyline that has been playing out across Hasbro’s toys and IDW comic books for the past year and the upcoming Activision video game Transformers: Devastation.
Insiders say it’s the first time these many synergistic elements have been combined by Hasbro to tell an overall story.
Additionally, Habsro is giving something a segment of its large Transformers audience has been demanding for years, namely an animated series aimed at an older audience.
“Our audiences are huge fans of the toy, comics, movies and video games, and for us to continue the legend with the Combiner War is a unique story-telling opportunity,” said CCA Daniel Tibbets.
Said Hasbro’s senior vp of the Transformers franchise, Tom Warner: “(Machinima is) the perfect partner to help launch a totally new kind of Transformers animation—one that, for the first time ever, is specifically designed for the teen and adult fans who’ve grown up loving the Transformers brand.”
Without going to deep into the complexities of the Transformers universe, Combiner Wars saw groups of Transformers be able to combine into one giant robot, known as a Combiner. Superion and Menasor were among the new robots that held the fate of the Transformers’ homeworld Cybertron in their hands.”
