At least if it isn't a hoax. The UK based website GameSeek offers GTA V PC for pre-order with a release date on 22 November. Despite many rumors, the PC version was not yet announced with a specific date.
It remains a little unclear if GameSeek can actually deliver on that date as we have seen this stuff happening a lot with pre-orders, but rumors have been there for a long time now. The game is offers for £24.75 in preorder.
Next to that on Reddit some guy has posted some screenshots of the PC version of the game, he claims to be a Beta tester. I think they are fake. But who knows. Check out the screenshots.
