I'd have to agree with that, but Slug Slinger is a part of Sky Reign, so unless he just decides to swap factions or they get someone else in there.. It would also be cool to see Galvatron counter Superion and write a Thrust clone into Galvatronus. Yeah. I's love to learn more about Superion's mental hacking skills.
Slugslinger's still not one of Galvatron's Decepticons, so I don't think he'd have any problem with just being freed from Galvatron's control and going along with whatever faction the other components want Sky Reign to be.
Predictions: Optimus defeats Galvatron. He doesn't overthrow the governments of Earth. They realize he's a swell guy and accept his alliance. He places himself and the Autobots at their disposal. The Autobots become, essentially, a perfectly accurate, perfectly non-lethal, nobly administered drone warfare system used to help out the underprivileged without disrupting the status quo. Sometimes they fight aliens or humans with alien tech, also to prevent disruption to the status quo. This will be billed as a "Revolution". It will be boring.
It's already been said that, as part of Revolution, G.I. Joe is called in to bring down Prime; there's that one cover that indicates they're working with the EDC as well. I don't think this arc ends with Optimus and the humans living happily together.
Another issue, another "Superion get´s it´s ass kicked" moment. Seriously, from getting ripped in half by Devastator to this, how many times did this guy got his ass kicked?
He's fighting four other combiners at the same time. I'd call foul if he wasn't getting his ass kicked. Regardless, it looks like he's about to be the one to overcome and take control of the Enigma (unlike Victorion or Sky Reign) and turn the tide, so I don't think this is that bad a moment for him. Declassifying IDW & Hasbro's World-Merging "Revolution" | Comic Book Resources And the cover. It could just be a variant that has little to do with the actual story, but I have my doubts...
My guess would be that Victorion is reformed by Enigma and kills Superion (busy working as a part-time programmer LOL), confirming Prime's dream in #50.
