Well. the update is here in downtown Aus.
Strange setup though. I went to App store and pressed 'update'
Several seconds later, it showed 'open'
Went to App and opened, and it stopped at 'need to download an additional 223 mb'
Did that and it stopped again showing 'need to download an additional 447 mb of data'
Now i am browsing through the latest update :)

Edit, just checked the new GT4 in Motorsports category and the Free trail for Porsche Cayman has 1st level of upgrades at 12 hrs and only 2 paint options
The 1st offer of new GT4 cars is for the Audi
