If the "two years in man hours" to create a track idea (as Matty posted above) is correct, I wouldn't be surprised to see Bathurst in either GT5 or a GT related trailer by the end of the year, possibly as a reveal trailer for the new Nissan V8 Supercar - as we all know PD has a long association with Nissan and have revealed new cars through a GT5 trailer, such as the Toyota 86.
FYI for others - Nissan is to be the first manufacturer outside Ford and Holden to join the Australian V8 Supercar series, and will be fielding a car for the 2013 season. See http://www.v8supercars.com.au/champ...ampionship/tabid/70/newsid/12124/default.aspx. Giving a Japanese angle to Bathurst 2013 means including Bathurst is a lot more relevant for GTs Japanese base.
