The first episode just premiered. The opening animation didn't contain any new animation AFAIK, but just used clips from the show, with some stock photos. The opening song itself was horrible, and really didn't fit the animation. I don't remember seeing anything changed in the episode (Update: Seems there was edits), though all the robots like announcing that they're going to "Transform" a lot. Music remained the same, except the opening/closing credits. The closing credits fit the show a lot better. I don't know who performed it though. Then we were cut to a group of 5 Japanese women who were playing around. They were transforming Bumblebee. The narrator from the show was talking to them... Then we got a skit about the Arms Micron. It was in really bad CG. Edit: I was making this thread and was just beaten here by 2 minutes.
