>>5917426They are haphazardly addressing it.
Alpha Trion's headmaster was recently revealed to be GW Blackrock and Sentinel's a headmaster.
Also Horri-Bull is dead in the comic and Nightbeat and Siren are currently at odds (Siren sided with Getaway in the coup, along with Blaster but it's possible Siren and Blaster were mindwiped/mindraped into betraying Rodimus and company) and far away from Cybertron/Earth.
All though,with Nightbeat, they have implied in the most recent arc that Nightbeat MAY be a headmaster (in the group video will, Nightbeat explicitly requests his head destroyed if anyone finds his dead body). Similarly, Astrotrain had his body destroyed and Galvatron was decapitated.
Most likely only a couple of characters will be Titan Masters, especially since it directly contradicts what IDW previously established with the role Titan Masters have, with Windblade and the "city speaker" gimmick.
At most, Galvatron and Astrotrain might come back as Titan Masters and Nightbeat/Getaway turning out to be a secret Headmaster. Siren and Blaster MIGHT be forcibly turned into mini-bots that turn into heads, depending on how the mutiny storyline goes as far as the two being punished and turned into such.
And they may bring Horri-Bull back to life as a Titan Master head bot, given that it's now a plot point that Optimus is blackmailing Soundwave into an alliance by threatening to tell Needlenose and other 'Cons about Soundwave''s role in murdering Horri-Bull to force him to bend the knee to Prime
