I think that will be one of the first things a reviewer will attempt. Especially with the Red Ranger, I imagine they produced more units just to attach the shield and arm bands instead of designing an entirely different suit to accommodate them. I could see the possibility of an Armored Black Ranger being another PX Exclusive in the future.
Not sure about the cuffs and boots. I feel they may be glued to keep the cloth in place but you'll definitely be able to know more in-hand. I'm still holding out hope for more Boom! inspired designs. I'm okay if they skip Evo I and II but I want to see Evo III so badly.
