Okay, I'm going to assume that one of the main reasons we haven't seen any new figure pictures for JoeCon is because they've likely been busting their collective tails for BotCon.
Now, we've all seen that interesting new insignia for the HeadHunters, that Cobra-emblazoned skull with the spears in the background.
Finding a place for that on the HeadHunter Guards was no problem. Finding a place for it on Gristle wasn't too hard, I suspect.
Where the heck do you put it on the Stormtrooper!? I've got a HeadHunter Stormtrooper here in front of me. Now, assuming the Club uses the exact same batch of molds -- arms and torso are out of the question. Between the spiked armor and assorted belts, straps, pouches, and sculpted-on weapons, there's categorically no room.
Legs are pretty much out of the question, too. Each leg has two straps leading to small weapons.
That leaves the head. And the top of that creepy techno-skull-faced helmet, although it's got a couple of ridges in it, IS a relatively smooth surface, and is really the only viable option. It's still going to have to be imprinted dang small, but look at how small they managed to get that Dreadnok insignia on the Dreadheads a few years ago.
I'm going with helmet. Discussion, anyone? Hopefully we'll find out soon!
(And yeah, this is the kind of nit-picky little detail that can drive me nuts...)
