PC is pretty weak on racing games. I doubt this is true, but it would be nice

GT home is on the PS and it need to stay there.

Apparently he did say this in this interview (using google translate from German):

GT 5 in my ''PC'' microsoft windows 7 ? ...cool,,thanks sony

I don't think it would actually be GT5 on PC, but rather a spin-off that would use the same assets as GT5 but had a microtransaction model which fits best with the chinese market.

Chinese market+PC games=99% piracy

The chinese games market is completely dominated by PC games and will soon overtake Japan as the biggest gaming market in Asia...

I know its dominated by PC games, people have no money to buy a console. The piracy there, however, is rampant. Only MMO's seem to work there.

No, but GT PC would probably be something like Need for Speed World Online, the Free-2-Play PC exclusive announced around the same time as Shift.

Unfortunately Grand Turismo won't come to PC. Sony ain't that dumb. There's too many pirates on PC.
