The Gran Turismo series shipped over 48 million so far worldwide, some interesting shipment data regarding Gran Turismo 4:
1) 2005/03/09 Gran Turismo 4 (Europe) 5.64M
2) 2005/02/22 Gran Turismo 4 (North America) 2.87M
3) 2004/12/28 Gran Turismo 4 (Japan) 1.23M
4) 2005/03/10 Gran Turismo 4 (S.Korea) 0.11M
5) 2004/12/28 Gran Turismo 4 (Asia) 0.07M
Europe's 5.64M is bigger than the rest of the world combined at 4.19M.
BTW, VGChartz seems to be around 1 million short of total Gran Turismo 4 sales (unlikely to be 1 million copies left on the shelfs by now).
