Gran Turismo "dropped the ball," Forza there to "pick it up"

[coolestguyever]

So did Gran Turismo drop the ball when GT3 sold just under 15 million or when GT4 has sold 9.65 million?

I don't see how they dropped the ball. It's more like Forza challenged them and Gran Turismo responded by adding damage, stunning graphics, nascar, and online racing.
