I actually think the opposite. I feel like PC's are ruining the gaming industry.. simply just because of their nature
Their prices, the fact that not everything works with everything, most games won't run on a mac or linux O.S. it's inhibitive.
There's GPU's CPU's Memory Hard drive space and many other things people need to think of with a PC game, one of the first things I see people do when considering a PC game is check the recommended system specs. Some games are fine but then you have things like Crysis which I don't believe will run smoothly on any of the current systems. This will change yeah but you'd have to buy an whole new PC for hundreds of dollars every few months to keep up or a GPU for the same prices.
The prebuilds that people normally buy in the department stores just don't have the power to run the high end games.
In the end yeah a PC can do more if it has the power but you can't make it for only the top end systems or it won't run on the low end ones. In addition having no set format and specs for PC's can be inhibitive, what is the sweet spot for performance and appearance who's gotta decide this?
I feel like I buy a console and for the next 5 years I KNOW every game I buy for that console will work on it and let's face it that's damn convenient. Most people don't have the time, money, patience or know how to update their PC every few months because some new FPS or RTS decided they'd have 30x AA(exaggeration)
Edit: I tend to keep my PC's updated fairly well but I cannot count how many times I bought a PC game got it home and couldn't play it or got some error message or my soundcard apparently wasn't good enough etc. Is it just me?
