Didn't know that, I entered at Gran Turismo World with GT3, it was crazy because I had a Nintendo 64 and my racing game there was an F1 game from 1998 and another game called Lamborghini Automovili it no only featured Lamborghinis but also Ferrari, Porsche, Viper Mclaren... it was fun but then a cousin put GT3 on his brand new PS2 and show me the intro and I was o god..... he also told and as you see the replay, in game is the same, from there there was no return, bought a PS2 just for GT3 and now here I am with the PS3 just to play GT5, I was tented to buy an Xbox 360 just to play Forza for Porsche but I had hope on see the brand on GT5, and yes there is also the G25 and the G27 only compatible with PS3 and PC so I bought GT5... still awating to see Porsche on a Gran Turismo Game some day....
