Went in to talk to my dealer today. The boss had news on the 'Aero' package available for the GTS model. Apparently it will be the Nur spec (as shown below). Though the down side is that it will only be available after the release date. So if you were to order one it would be built after the 20 June launch. Where as the normal GT and GTS model would be built on order.
This information was given to him from his area manager; who in fact saw the car at the Gold Coast. He also described it with a big spoiler with fins and with a full body kit.
