Considering that it takes about 8 weeks to for a company to normally manufacture a group of uniforms and most guards were still looking for people to fill holes 3-4 weeks ago, it is possible to not see the uniforms on guards for another few weeks.
As a guard instructor, I would not debut the uniforms until EVERYONE had one.
Last night was the first show of the season... Some groups hold back until everything is complete, and then there's a HUGE jump in the visual scores. You have every right to complain, but just so you know, many of these things are out of the corps control.
