I totally missed the announcement of the Universe this story is set in, as it was tacked onto the bottom of a shortened version of the banner on their website.
It was the tweet that they wanted re-tweeted 250 times that I posted about above, but I didn't click on the image to look at it, thinking that it was just the same banner as on their website. (I actually just shrugged it off as yet another unfulfilled promise of theirs.)

In the city of Axiom Nexus, in a Universe where Autobots and Decepticons from across the Multiverse co-exist peacefully, a group of renegades operate off the grid, using deception, scheming and a hint of thievery to both survive and to further their own ambitions. However, after the Transtech, the guardians of Axiom Nexus, are unable to stop an extra-dimensional threat, these outlaws will soon find themselves as Cybertron's last best hope for survival!

And since they reached their 250 target, they have now released the preview page (pencils), and there looks to be a number of IDW universe characters in it.

I think it says Matt Frank at the top as the artist for the 2015 comic.

I can see Windblade (actually two???) in the bottom panel of the page, and I think Skybyte... those who follow the IDW comics will probably recognise more of the characters. Maybe the Windblade mould is being used for a couple toys this year if both at the bottom of the page is her mould.

The giant fem-bot head had me immediately thinking of Marvel UK Auntie, but it might be something in the IDW comics that I haven't seen yet.

And since the BotCon comics recently have been throwing in non-Transformers Easter eggs, is that a Dragon-zord or Zoid in second panel, or a Transformers character from the IDW comic that I'm just not recognising?
