In some of the initial press information I believe I saw a GTS blue ACR test mule complete with the old 10-spoke wheels but as far as I know they did not make any actual GTS Blue ACRs for sale to the public. You could, however, take an ACR and have it sent to Prefix for their "1 of 1" program; they can custom paint the ACR any color you wish, including GTS Blue.
I personally hope that you do it; I would love to see an ACR in GTS Blue, maybe even with dual or single white stripes.
