The new model will have a stand-and-fall "mandarin" collar, VELCRO closures rather than buttons, and will be made with a digital grey-green-light brown all-terrain pattern camouflage system. (I've seen this new camo, and it's VERY light to the eye...seems grey at first glance...more, my experience with VELCRO closures is NOT good at all...)
Boots will be replaced with "no shine" tan combat models for both cold and hot-weather uses.
BONUS...be prepared for a HUGE surplus of old "woodland" camos and black boots within the next 18 months.

Further, the USAF is also looking for its own distinctive service "work-utility" uniform...no style or patterns have been agreed upon, but they are looking at both the Army and USMC summer-desert digital patterns, with perhaps a few changes in the construction.
