Ordered a 2015 S7 but I am now told that 2015s are unavilable and my car will be a 2016. Does anyone know when the 2016 S7s will be available?

Now being told that my original order has been released to production BUT the dealer (via accessaudi) does not know if it will be a 2015 or 2016!!! Does anyone know the production status of the S7s??? OR do I have to wait for the VIN to know what year I am getting..AUDIUSA was unable to help :-(
