Okay, I had to let this one sit for a while and re-read it before I really commented on it.
First, let me say, Livio, dude, the cover to part #3 is one of the single best images of the entire series. That's not meant as a slight to the interior panels on which you've done so well; the cover is that damn good!
Optimus/Orion's line "Autobot jurisdiction is what we say it is" is really, profoundly unsettling. It's basically the same thing the Senate enforcers told him in Ongoing #23 when they came to spring Whirl from his cell. It's such a non-Optimus Prime line that it really made me uncomfortable to read it, and it shows just how damaged and corrupted he is at this point. I hope Metzen and Dille's script for this series delivers a hell of a redemption and turnaround for this character, and it'll be interesting to see the catalyst for his change.
Finally, I need to talk about Soundwave because this was his issue and it was terrific. What impressed me the most, though, was that it showed me an aspect of Soundwave that I've never really realized before: Soundwave is an assault team. The Cassettes are individual Decepticons, yes, but they're also Soundwave's weapons--and they're extensions of him. When Soundwave goes on a mission, it's really five or six Decepticons on a mission. The way he uses Ravage and Rumble and Frenzy (I've never liked Ratbat--kind of wish that had been Laserbeak or Buzzsaw) were so brutally and tactically efficient that he was able to--for a while anyway--fend off the pursuits of half a dozen deadly-ass Autobots.
The panels where Ravage "eviscerates" Hound and Bumblebee... I can't tell you why but my mind flashed to the killer rabbit in Monty Python and the Holy Grail. I didn't laugh, of course, but I did say, "Holy $#@%!"
Great chapter to a very enjoyable series!
