I have a post on my facebook feed with the new helmet design, and I'll say the same thing here that I've said there. These look AWESOME!!!! I'm a huge clone trooper/ storm trooper fan and I think this design looks perfect as an advancement over the previous storm trooper helmet. You have to figure that technology and kit would improve for troopers over 30 years from the time of Return of the Jedi, so this looks like a good progression in design, fit and functionality. I see great potential for customization with these masks and hope we'll see more trooper inspired personalization of helmets and armour in the new movie, like clone troopers did and like a lot of soldiers in modern armies do right here and now. If you really look at the helmet you can see a strong influence from the Imperial storm trooper helmets and can see how this would be a natural progression made through advances in technology and input from troopers for improvements that could be made with their kit. I can't wait to see what they do with the armour. Personally I'd like to see them actually kind of bulk down the armour some to give the troopers some more mobility and leave room for more bulked up armour in troopers in special divisions/ special applications.
On a more personal note, I'm hopeful some company out there that manufactures paintball helmets will be able to get ahold of this design and come up with a functional/safe version to be used in playing paintball. I could see me having fun making a fun custom version to go along with my own kit for paintall.
