I heard nothing of GT4. But I have heard of plans of making an online Gran Turismo game. the harddrive will be used for downloading new cars and data. And it will finally be possible to race against other people.
Kaz also said that he is not very happy with GT3 (obviously not in those words) because he did'nt have very much time to do it. And i think he also said, that they are going to completely re-design the GT4 code.
Oh, OK. I believe I have seen a picture of one of Sony's Japanese press conferences, and there's a large display with the letters GTN on it. That's good.
I was never much of computer person either, that is until gtplanet was made, now I'm on here 2 or 3 times a day. Gives me something to do on my summer vacation.
Yeah, it's a lot different when you have your own website. I feel like I'm on here 24/7. If I'm on the computer, I'm either finding ways to get the word out about GTPlanet, or looking for ways to make it better.
