Still reding the IDW Transformers books, and they're still good. Til All are One just got canceled, which is a shame, since it really was good.
Quick update on the status of the major books, well into the post-war era:
The Lost Light: Rodimus's mistakes as captain came back to haunt him, as a mutiny left him and his core supporters abandoned on the Necroworld. (graveyard planet) The group barely survives an assault by the Decepticon Justice Division - don't laugh at the name - these guys were frikkin' monsters. There was an alternate dimension story, and now Megatron is trapped there, where he became a hero.
Optimus Prime: To protect Earth from Galvatron's invasion, (Megatron and Galvatron are seperate characters here.) Optimus annexes Earth into the new Cybertronian a Council of Worlds. Earth doesn't want that, since Megatron and his army wiped out over a billion humans during All Hail Megatron. Prime breaks his code of honor and executes Galvatron after the tyrant surrenders. His followers, including a cadre of religious fanatics who worship the Primes, start to doubt him after that. One, the leader of the Victorian combiner team, might be plotting to usurp Prime. A nearly disastrous first encounter with the Junkions and their Sharkticons didn't help.
Til All are One: Starscream is still in charge of Cybertron, and does whatever necessary to stay there. He's also mentally unstable, as he constantly sees and talks with Bumblebee, who has been dead for quite some time now. There's a lot of politics in this one, where actions really feel like they have consequences. There was a great Bruticus story, and Sentinel Prime, who is never not a dick in any version of TF lore, attempted to use a reanimated Titan force (Metroplex's kin) to take over Cybertron and purge any bot he deemed impure.
I was afraid when IDW united their titles under the same universe - TFs, GIJoe, MASK, and ROM - the books would suck. Fortunately, they've shown appropriate restraint. Really, only GIJoe, which is basically a global response team to deal with the Cybertronians, only shows up in Optimus Prime. It's done in a way that makes sense.
