To be fair to AHM, McCarthy was originally told it would be a complete standalone run that was an alternate universe take on Transformers.

IDW were being indecisive about what to do with the -ation series and decided late on in the process that AHM would actually serve as the next part of the main continuity.

Also the DonFig Ongoing Bayverse G1 mashups were absolutely epic. I'd love a toyline done in that style.
