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

This was pretty insane to read. People generally underestimated Uncharted 2 and God of War 3 by quite a lot, and overestimated Gran Turismo 5 as well.

That said, I think GT5 has the legs to reach a much higher number one day.
