The developer of Gran Tursimo PSP and Gran Turismo 5 has beefed up their staff.

Although the situation has improved in recent iterations, for much of its history the Gran Turismo series has been heavily criticized for its engine sounds. During the PlayStation 2 and 3 eras, engine notes were often compared to "vacuum cleaners"; the result of synthesized loops that lacked the soul and mechanical violence of their real-world counterparts.
Video games sounds keep evolving with every new generation be it a little or a lot eventually it will get to the point of been inside the race car

Former Sony Interactive Entertainment executive Shuhei Yoshida has shared how his feedback played a role in the success of Gran Turismo.
To this day, anyone that plays a GT game for the first time and doesn't have experience with this kind of game will crash at the first corner, so not really sure what Shu is claiming here. I literally saw this happen a few months ago at an event where they had GT7 with VR2 up on a stage and members of the public got to try it out.

Nathan Williams from Bebington has made a dream leap from virtual tracks to real-world glory, clinching victory in his debut race in the OT Coupe with Toyo

GT 5 coming to get the 360 in 2009. Perhaps PD should just announce it already so that the guys at Turn 10 can stop having constant nightmares.
I don't want them to release this gem till it's ready to go up against a biased media.
To have Gran Turismo for PSP ready for 2009, I imagine that Polyphony HAD to hire more people to get it done in time. More employees definantly is a good thing, because maybe then GT5 will be coming sooner rather than later... hopefully by the end of the year, but if not, I hope it's not later than Spring 2010.
Polyphony Digital need to get this out, cos if they take much longer dam 3 to 4 years for both psp and ps3, And when everybody starts bagging Forza 3 out, and don't get me roughing I love gt5, But The wait kinda kills it, well for me any way, but I don't think will see it at Xmas this year maybe japan will, but none of the rest of the world, I hope they don't stuff it up:)
