No, because concept cars are released with the understanding that they are CONCEPTS

. No one expects them to come to market and the companies don't put release dates on them just to break said release date and push it back further, and repeatedly (although GM did do that with the new Camaro's, but we all know how well their business model has worked out for them).
The ACR on the other hand, was debuted with the understanding that they would be available for sale within the year. All the testing was done, and production was just being ramped up so that stock on hand could have a chance to match demand come the release date... yeah, right.
They aren't going to be released, quit holding your breath and go shoot a gun that actually exists.
