Ep 3 is online.

The whole thing is pretty much a flashback sequence, showing how the Allspark came to leave Cybertron. Of note:

*Neither Welker or Cullen are doing the voices, though the new voice actors do a reasonable job of impersonating them.
*The Seekers seem to be going to be used like the Vehicons were in Prime, as in there are tons of them to be destroyed. Saw some in completely new colours and there were tons all in Sunstorm'ish colours.
*More evidence that this is not the same continuity as beforegiven that Soundwave talks and Grimlock looks nothing like the RID version bar that he has a mouth. Also Windblade was friends with Bee on Cybertron and not Earth. The only way it could be the same as the Prime/RB/RID universe is if a LOT has happened between the end of RID and this.
*The animation seems less impressive than before when you see it try to represent bigger fight scenes.

So overall, underwhelming.
