From IGN.

PS4-exclusive Bloodborne could be coming to PC at some stage, if a retail listing is to be believed.

The listing, live at the time of writing on Amazon France, lists the platform as "Windows 7/8" though it's "currently unavailable".

Amazon France has previous form in accurately leaking game details before publishers are ready to reveal them. To date, its list of scalps include Call of Duty: Black Ops II, the Killzone Trilogy, the European-only Assassin's Creed Anthology, Grand Theft Auto V on PC and a PS4 bundle for The Last of Us: Remastered. All of these turned out to be accurate.

Is a PC version a possibility? Is that forgotten extension of the trademark for Bloodborne something to do with this?

What are your thoughts?

ughh.. its not gonna happen. people might as well also beg for uncharted and gran turismo to come to the PC. maybe mario and zelda too.

lmao no, its a error

Not going to happen. It's clearly an error.

Lol, I know this is a looooong shot an impossibility, but since I might take a long time to get a PS4, if a PC version miraculously comes out, I'd get it day one .

Yes, Cause Sony can increase it's consumer base on the Ps4 by releasing this on PC, just so people don't need a reason to buy a Ps4. I guess this is Wishful thinking at it's best :P Microsoft jumping over to Windows and releasing it's exclusives on PC was pretty much the biggest steop since E3 2013  which is contributing on slowly killing their XB division. i doubt Sony would ever do the same. They have said at several accounts: We are in the console buiz, so we ofc will focus on consoles.

Sony owns the IP and it's co-developed by SCEJ, so maybe when hell freezes over.

I doubt it will happen, scej worked also on it. What people might could see is a spin off from bloodborne the same way demon souls turned into dark souls for multiplat.
Even MS slowed down with PC ports, we havent heard about sunset overdrive coming to PC for a while.

Still keeping that non existent hope alive? lol

Well if Sony allow then it can happen.

I just need to check the last game Sony allowed to be on PC.
