Have consoles held back PC gaming?

[Pooky]

When you talk about "held back by consoles", are you specifically talking about visual quality of the games?

Yes mostly, but also with game mechanics/engine etc.

I'm no game dev, but surely PC processing power allows for more complex engine design and features, and this will also be held back.

Not to mention PC input is not limited by the buttons on the console controller. We already see how this blatantly puts PC users at a disadvantage with examples like Skyrim and Oblivion, which had crappy inventory management, solved somewhat by mods on PC, while Morrowind's inventory still is way ahead.
