So, I just came back from my LCS with this. The interviews are nice, but there's nothing really new apart from the typical "You're Gonna Love This because" jive...except this time, they couldn't be more right, by the looks of things. There's a Roll Call section, listing who apparently will be some of the major players in the series:
Slight spoilers below, highlight to reveal. Nothing really major, but just in case, as I don't want to ruin anything for anyone unless they want to know:
ponycorn, you want Insecticons? Your wish is granted:
Roster:
Insecticons
Constructicons
Astrotrain
Blitzwing
Skywarp
Thundercracker
Starscream
Soundwave, Rumble, Frenzy, Laserbeak, Ravage (no mention of Buzzsaw or Ratbat)
Megatron
And we are finally granted an answer to a question that has been nagging us since IDW got the license: RIRFIB. 
Now, the preview itself...
Scene opens with the Constructicons transforming in the middle of a very busy intersection on a street. One passerby thinks this is amazing and wants pictures. Scrapper informs the masses that they are here on a mission of peace, cooperation and goodwill.
Then after a brief pause, and an exchanged look, he and Hook proceed to laugh their asses off, right before they all start opening fire into the crowd. Mixmaster comments on how soft the materials humans use for construction purposes is.
The Seekers arrive on the scene, and Starscream, cutting loose with some fire, revels in the fear and terror the squishies are all exhibiting. Skywarp says there'll be more once Megs arrives. SS of course says's he's the master of these things, not...
..and he is cut off, as Megatron is standing behind him, arriving earlier than expected. He calls out Starscream's supposed acts of 'destruction' by hoisting his fusion cannon, and firing it.
Last page: As an immense, glass-windowed office tower topples to the streets in the background, Megatron says that Starscream thinks too small.All hail Megatron, folks. We don't have a choice.
