You wish.
I just checked Amazon's Top 100 PS3 games an hour ago. There were three racing games on the list, and they were all Gran Turismos -
two of them were GT5. #23 was GT6, 65 and 85 were GT5XL and GT5 respectively, go figure.
All other Playstation racers, in fact,
all other racers period, are essentially flashes in pans in comparison. Even with supposedly superior games like GRID A., gamers want GT. You could argue that it's pure reputation that has all these people going for it over other racing games, but reputation only carries you so far. And it has been mentioned more than once that what vexes the purists to no end like Standard cars and poor sounds are mere mentions to gaming journalists, and fans don't really mind. We just want to race. And I'm about to.
As for the fate of Gran Turismo and any reveals this year, we shall just have to let time pass.
