It's looking like Hux will be in the next wave/batch along with Luke, Leia, Han, Snoke, Maz and whatever other characters will fill the remaining spots. And given that there are four main bad guys (Hux, Phasma, Kylo Ren, and Snoke) it makes sense to split them evenly across merch releases.
I always loved the figures with removable helmets like Boushh, Skiff Lando and the Ewoks. It's also another reason why I absolutely loved and still love GI Joe and totally fell in love with M.A.S.K. as a kid. Well the freaking awesome vehicles that transformed and the cool mask powers also helped. LoLAre we sure this is a non removable helmet? Dissapointing if you make an alien figure and you can't see the whole alien's face?! If they think kids don't care about these things think again. My friends and I were as elated as could be in 83 when when we found out Boushh and Skiff Lando had removable helmets. Way to trip and land over 30 years ago.
