This is a piece of breaking news I have just recieved from Chris Allen from GlobalF1.net.
He says that the GP3-2000 add-on may have been delayed in the UK until September 14th. This all becomes clear in what he had to say:
...whilst I was in EB ordering my copy of GP32k this afternoon I was told it's been delayed again until next Friday (September 14th). Apparently they had only just heard about this...This is bad news to all fans in the UK awaiting the GP3-2000 arrival (due tommorow). If you find the game in stores tommorow, let others know on SimRacingForums.com.
