So that's how you're going to be about it huh?
PGR3 is far far from accurate as a racing sim. It's definetly leaning more on the arcade side of things. Real racing is all about taking the highest exit speed out of corners; and that's best achieved in nearly all cars (on a normal track) by maintaining grip on the wheels, while accelerating out of the corner, not drifting around the corners at 200km/h.
So instantly, your opinions are struck out by your own ignorance. GT4 isn't the most accurate racer in the world, but it still does do a relatively good job of things, and definetly still compares favourably to PGR3 in terms of accurate handling. Now, if you want a game to feel like PGR3, then GT isn't for you; it's not about semi-plausible, but really actually arcadish style driving mechanics; it's definetly more about simulating a wide variety of real world cars and vehicles as best as possible.
I won't comment on what you said about AI; except to say that, it's pretty shallow that you can't appreciate just driving around the track to get better times (which is GT4 in its strongest form)... which is interesting, because PGR3 is at least in part a lot about that kind of stuff (driving around the track to meet challenges; not just racing other vehicles).
Also from the sounds of things, you haven't bothered to pick up a FF wheel... if you really did love driving games and wanted to appreciate them as a simulation rather than an arcade game, then it would be a given. Well, in that case, GT5 will do it's best to please as it will no doubt have support for Logitech's new G25 wheel (leather bound, solid metal steering wheel and pedals, as well as a seperate 6 speed gear shift unit... of course, 900 degrees turning and FF too).
As for the sound; it's flat because of the way they've recorded the sound.
Also PGR3 has great sound, not because it's accurate to the cars, but because it has positional audio; rear engine cars have the engine sounds coming from the rear (if you have a 5.1 setup), while bumps/grills on the road has a very convincing passing underneath you effect.
I'd think with the PS3's increased power, they'll be able to incorporate those elements much more easily then in previous GT games.
As long as they go to the effort of recording the sounds properly this time; with the cars running on dynos; allowing them to rev the car up through the gears and not just in neutral, things will be good.
In short, nobody should listen to your rantings.
