Except you don't know that. In fact it does it goes against Sony's own statements. Where's Dreams? Where's Demon Souls?Bloodborne is an exception. Playstation gamers aren't even getting a patch for the game let alone a port to PC. Japan studio is gone and FS are busy doing other things.
Gran Turismo was on the Nvidia leak list. It being online only makes it very likely to join the list of ports in the future. Just wait till the sales dry up on playstation and watch it get announced on PC.
Like I said the port begging is unseemly. The denial that's it's port begging is just amusing. And I say this a PC owner myself.
