You know why graphics have been improving less and less recently? Because of a thing called diminishing returns. That's all.
The difference between an object with 100 polygons and one with 1000 is huge. The difference between an object with 100,000 polygons and 200,000 is negligible.
Consoles are in now way holding back gaming. Gaming is first and foremost about gameplay. A game which emphasis on graphics over gameplay is something which would work better as a CGI film than as a game.
There's really no point in discussing Polygons, because that is irrelevant. (mostly)
What it all comes down to is Textures when we are talking about Graphics.
The 3d Models, in most video games, are pretty good. The problem isn't the 3d models. Its the Textures. Consoles have limited Memory, and textures... take up far more memory than 3d models (kinda). There are far more gains
graphically, for the PC to scale the Textures up, than to increase the polygon count 50%. (this plays into shadows, and all those annoying graphic-card burning hurtles it jumps through)
Simply having better textures, will increase graphics a staggering amount. (look at Morrowind mods for that example! Ultra-low (by todays standards) polygon counts. Ultra-high Texture quality.. And it looks, just below skyrim, in quality of graphics.)
One of the tricks they did in Metal Gear Solid IV, was pretty interesting.
What they did, was simply make ultra-high quality polygon models, with ultra-high-quality textures, with the best lighting/ect. They then used all that data, to make
textures that kept a lot of that shader-detail, so they could apply it to a lower-polygon-model, while keeping much of the shader-quality. (to a point). They obviously scaled down most of the textures to fit the PS3's memory, but.. Hell the game still looks great in 2013.
But they added even more tricks up their sleeves.
Why make a texture of a.. say face. If that face is Symetrical... why does a 1024x1024 face texture.. Need to be of the full face, and not the half? if you instead, make a texture that is 1024x1024 that is even more detailed half-of-a-face. And simply mirror said face on 3d model. Your getting more texture quality, while using less memory. (I'm guessing they somehow only loaded the texture into memory once, not sure how it doesn't double up by mirroring it, but that's what they claimed they did at least)
And if that didn't work, they could just have easily, made a texture that was 512x1024 pixels, using about half-the disc-space, and about the same in-game memory.
They did a lot-of-tiny tricks like that. (I believe this site even had articles all about it, prior to it being released.)
In Short:
To get more out of a game graphically simply upping the polygons is pointless, if your textures look like horse-shit.
Most PC gamers, just want higher quality textures. It achieves the same end-game-purpose, without using as much resources. Vanilla Skyrim on the PC, Looks like crap until you get in some nice HD textures.
