Can't say for sure until Sony actually shows the PS5 and we get info on specs, price, games, etc.
But with the recent Horizon news PC is looking more likely than ever...... IF I can afford it by next year.
Even just having a laptop with a crappy 1050ti has given me a taste of PC gaming and it's hard to go back. More customization options, mods, MUCH cheaper games (thanks regional pricing!), free multiplayer, emulators, decades worth of games. Not to mention that this was the gen when most Japanese devs finally embraced PC too, which was one of the big reasons I always preferred consoles
Sony exclusives are the one thing that still has me interested in Ps5 but if they'll start coming to PC, even if it's several years later, I don't mind waiting.
