Especially if they go super in-depth into Hwang's role in the navy, having him going out doing stuff for the coast guard, dealing with Maxi's pirates, and all that, there wouldn't be room for an appearance. Though he could get a mention, since he's already gotten one from Mi-na in Libra of Soul, nothing wrong with saying his name. Hilde's name was also said in Libra of Soul. Setsuka's the only one who was really "absent", except that one line in combat lessons.
But then again, if that were the case, then Aeon deconfirmed for season three because he appeared in Grøh's side story chapter right off. (I don't think it was Aeon, actually, based on the fight afterwards, but they used the Aeon portrait with his unique armor that's still not in the game for some reason.)
He was only shirtless one of three games he appeared in, so I don't even think that's part of his iconic charm. Even then was kinda weird, he looked like he was spending too much time with Maxi, looking more like a pirate than a swordsman. But just because he wouldn't appear shirtless doesn't mean we wouldn't get to see his abs, he could just have a SoulCalibur III style vest or something like that. But armor break has definitely been trending towards getting all the guys shirtless eventually, unless you're Raphael, only backless for him...
