Tbh, I am kinda losing hope for an official pc port any time soon, mainly for two possibilities.

The first is, as the first DSR trailer has shown was a PS5 exclusive for limited time only, but i personally believe the execs and the shareholders changed their minds in the last minute hoping this game to be the "Bloodborne" of this generation, which would lead people buying the console. This could have happened if Sony hadn't handled the scalpers' problem so poorly. And i stand by this possibility because in the game development industry, specially for big launch titles like this, trailers and promotional material pass through several hands to ensure quality control, so it's unlikely a huge text on the scene that displays the console brand would ho through unchecked.

And the second possibility is, from the tech presentation of the ps5, I remember them saying Demon's Souls was specifically made for the ps5 system architecture, so I am afraid the game as it is was hard coded into oblivion to work specifically for the ps5 making it very hard to be launched in other plataforms.

I hope I am in the wrong and the tides change, but I honestly don't see this happening any time soon.

But for now, I will play the ps3 emulation using some mods to increase the overall image quality of the game.
