Some people need to get out a little bit more. The same argument goes around in circles and it can't possibly be concluded on a forum due to so many variables.
I've said before and i'll happilly demonstrate to anyone in person, GT5P actually sounded ok on a decent sound system, and by decent i mean real speakers and a real amplifier, the engine sounds drive emotion as long as you play them loud enough, ie, at levels you would experience if you were actually racing.
GT5 looks to have improved sounds, first hand experience of demo setups back this up.
Anyone putting all thier faith in:
crappy computer speakers;
playing exceptionally compressed youtube videos;
through a web standard, flash, which isn't exactly known for it's high fidelity;
through cheap soundcards;
recorded at a varying range of quality;
by a massive variation of recording equipment,
at poor positioning to the stereo of the speakers,
in a noisy enviroment;
by a TV that isn't capable of playing a fraction of what the ps3 can output, and is also desgned to be placed in a living room enviroment, close to the walls;
cannot possibly make any factual statement if the game will sound like it should when i take it home and play it on my system.
Based on some of the statements in here, i could use the same logic to say GT5's graphics are crap because of the quality of my camera phone taking video footage from a black and white tv, pointed directly into the sun over a coax lead because if doesn't even have scart.
