I don't think that they managed to get a ACU one pattern fits
all solution in the end, afterall, as the photos (this thread, page
1) show, prints used are obviously just digitized versions of
desert camou rather than a grey tone uniform.
The photos showing the USAF general in digitized grey scheme
uniform cannot be taken into consideration. The USAF regards that
uniform as a utility uniform not combat gear. The reason is that
the majority of USAF personnel wearing such uniforms don't need to
be fitted in combat gear (Most ppl who wear utility uniforms work
in service side).
For more info abt USAF uniform change, you can refer to the USAF
website listed below, the website is slightly out of date but most
of the facts remain the same:

The original utility uniform proposed was a tiger stripe blue
(similar to Vietnam era). The version shown worn by the USAF
general is a digitized version of that uniform.
