You are forgetting two things:
1) PC's require a bit more ''horsepower'' to run games at the same level as a console does. Consoles utilise their weaker GPU/CPU better than a PC with the same set would, because they are machines optimised for gaming + there is no variance in specs which makes optimisation easier for devs.
2) The GTX 980 is for 1080p/60FPS, which consoles cannot achieve + Hairworks and some other little bits and bobs. If you were to run the game at 1080p/30FPS or 900p/30FPS the specs will scale down closer to console hardware, even more so without hairworks.
Basically yes, there isn't a huge difference between PC Ultra and PS4, yes the drawing distance is a bit better and you'll have things like Hairworks. But people who did call the visual parity statement from earlier this year ''PR move not to upset console players/M$'' is simply BS. Does the game look amazing visually? Hell yes it does. Are there clear differences from what we were shown in promotional material way back? Yes. Am I mad bro/brah's? Nope, the game looks good and every other element (gameplay/story/atmosphere) looks fantastic so I am totally pumped.
I'm going to say here what I said in another forum. PC gaming has never been about balls to the walls graphics. It's always been about scalability, or using settings and tweaks so you can adjust the game to fit your hardware's capabilities.
What I find irritating about the Witcher 3, is that CDPR has left very little room for the scalability of assets and effects. Even worse, is the outright removal of certain effects due to the consoles. The blood decals should never have been "CUT" simply because consoles can't handle it or whatever. It's just a graphical effect, and doesn't affect gameplay whatsoever so why cut it out?
Thats what settings are for. Leave a way for those to enable it who can run it..
