Not being one who follows the current comics... at least, not as they are being released... I'm guessing that this "chapter 1" issue of the 12 part Dark Cybertron story is not a RID or MTMTE issue. More like a stand alone issue to introduce the other parts that will still be numbered as RID and MTMTE.

(because I couldn't find an issue number or name for either of those two series)

Anyway, for those keen on jumping on board at this time, for the next big chapter of IDW's Transformers, a preview of this issue has been released, and the comic should be out in stores this week.
