UPDATE: GT5 passes 10 million - Guess the lifetime sales for Uncharted 2, God Of War III and Gran Tursimo 5

[Carl]

Uncharted 2 - 2 to 2.5 Million

God of War 3 - 3 Million max. PS3 can't cupport games like PS2 could.

 Gran Turismo 5 - 5 Million max. GT games always sell less if they've already had a game on the console.
