So here's the 5 page preview.

The issue will focus on Hotord and his exploits since leaving the Earth based TF a while ago.... Art by Nick "LSotW" Roche, Costa still on the story duties.

What strikes me as odd is the blurb, namely the bit I've bolded... :
RODIMUS might be impulsive, but he’s not stupid. The last anyone saw of him, he was rocketing off Earth in disgrace and a stolen ship. In this issue we finally see where he went, what his plan was, and which long-absent DECEPTICONS he came up against. Mike Costa and fan-favorite artist Nick Roche deliver a stand-alone issue that sets up the entire second year of the hit ongoing series.
A stand alone in the middle of an ongoing? I get that it is a standalone in where the focus is for the story, but it is still part of the series as a whole, rather than a sub series or spotlight issue.

And those who hated certain parts of the last Indiana Jones (Crystal Skulls) should probably skip this one...
