If Grand Turismo 5 is released in 2009, could PS3 close the gap with 360?

I think that we shouldn't say omg this one game will save the ps3. But because the ps3 is now getting sooo many excellent exclusives that people are just going to go I have to have it. But yes I think Gran Turismo 5 will definately increase ps3 sales
