I've not examined the photos enough to say one way or the other but I'm guessing what happened is whoever was tasked with this figure at Hasbro perhaps carved out a CT Trooper helmet to work as the removable helmet... I dunno.
With it being basically an inferior sculpt (the commtech trooper that is, overall) with a helmet from dubious origins, I'm not particular if they did just hollow out a CT helmet and put it into production or if it's an all-new sculpt... It's all meh to me.
