I bought PS3 only because GT and thats how it's going to be. I have no interest of any other games, than racing-sims, and so long than I can find good competition I aint going anywhere.
I hope that this slow improvement of GT5, will frustrate most of those drivers, who I dont wanna see on track anyway. (read:kids,morons,punters etc etc...)
Ofcourse I would like to see even few good tracks more, but it will suck back some worse part of GT5P-owners too. I rather race with 3-5 good racer, than full-grid with tourists.
More than privaterooms, I would like to see example 20-30 laps races with tyrewear and fuel-tactics. I also wanted to have somekind of 'extreme-lisence', what you could not download anyhow, and to earn it, you should do very very hard tests. Ofcourse those extreme-events should be extreme-simulation of racing too.
