i think HT has something up their sleeves with this DX that prevented them from showing it. i think that its going to come with a battle damaged chest piece to go with the mouth, why would they include a damaged mouth from the end scene with a totally clean fig. maybe the system that will allow you to change it wasnt ready or maybe the BD piece wasnt ready. this is my guess cause i cant see another HS being added in.
I'm guessing (and hoping) that the battle damaged emblem will be included too. Just makes sense with the bloodied mouth.
You could get away with not having a battle damaged cowl since the scarring was minimal on it. But the emblem was clearly scorched along with a bloodied face as he emerged from the Batwing wreckage.
