It seems to me that we don't need that quote to tell us that the PC version is indeed being held back to match the console versions, I mean, Todd Howard himself said when asked about the subject of whether the game would use DirectX 11 that they aim to make the game look the same on all systems, and that even though the game does support it, it wouldn't take full advantage of all the impressive features it offers (I guess the advantage that using DirectX 11 when playing Skyrim would offer is only a performance improvement.) but really, that's no shock. Didn't Todd say that his favored platform is the Xbox 360? So naturally, he wouldn't want the other versions to outdo it. I suspect we're not going to see an Elder Scrolls game that is not limited by the capabilities of the current generation of consoles until the next generation comes, and of course, it may be that the PC version will still be held back by THAT generation's capabilities, if by the time the game is released PCs have advanced beyond the capacity of the new consoles.
It's not so much a matter of what we're use to, as it is what our rigs are capable of dealing with.
It's be like owning an Xbox 360 and being given PS2 games to play.
And yet even though I have an Xbox 360 I still sometimes willingly play a PS2 because I happen to want to play a game that's available on that console.
But I see what you're saying, I just wanted to say that because it seemed like a bit of a flaw in the anology. Probably a better anology would be if a Xbox 360 owner got a game for the Xbox 360, but its graphics were on the same level of the PS2 since it was also meant to be released on that console.
