Found this video on youtube showing acceleration difference between the 2009 and 2010 GTR and they also ask Mr. Mizuno to elaborate on the launch control controversy surrounding the car.

YouTube - 2010 GT-R - GT-R Launch Control Controversy Explained

I find all of this very hard to believe. I think that Nissan really dropped the ball with the marketing of this vehicle and now are scrambling to do damage control. Even all the BS about the 7:29 Nurburgring lap. There's no way a stock GT-R could do that, and it has become pretty obvious.

It's a shame too because the car is pretty impressive and could stand just fine on its own merits. Despite all that I have one on order.
