The previous adult-targeted Transformers cartoon was uploaded to the now-defunct Go90 website, which is now available through Rooster Teeth. After the conclusion of the Prime Wars Trilogy line Hasbro started a new collector line called “War For Cybertron” (not to be confused with the video game because Hasbro doesn’t pay attention–see also Robots In Disguise), which is meant to be a return to the original G1. The first line in the new trilogy, “Siege”, takes place on Cybertron and allegedly involves Cybertronian modes, though there wasn’t a lot of imagination in some of them. Optimus Prime is just his usual flat nose cab with some extra lights. There have been better Cybertronian modes for Op.
Like with the Prime Wars Trilogy the series promoting it doesn’t start until sometime AFTER the toyline has moved to the next series (in this case Earthbound…not to be confused with yet another video game that at least wasn’t Transformers related). This time it’s Netflix that will host the series, meaning if you can’t afford Netflix, like yours truly, you’re out of luck. We do however have a trailer for the new War For Cybertron: Siege animated series (which the trailer calls an anime, a term used for animated series out of Japan…which this isn’t), so let’s see if I’m missing out on anything.
