The reason Console gaming is so popular and lucrative primarily resides in two points (in general):
1) People who don't understand how to properly use computers/know what parts to buy.
2) Children
That being said, of course there are other people who use consoles who don't fit in those categories. But usually console gaming's lifeline takes the form of those two. Consumer trends makes the children cling onto consoles more for future money-wasting.
I'm a PC gamer, and I find it more freeing for a bunch of reasons. The biggest one is the customization in both graphics and versatility. Also, when you have Steam, it lets you keep all the games you have digitally, which is obviously better than losing a bunch of discs. I also know that my graphics card is more superior than those in the console.
Some issues: You have to get new graphics cards and processors over-time. Unless you buy a really high-end card, you'll usually find yourself replacing them more than you are replacing consoles. It also requires a little more maintenance than a console.
Also. If your working computer is the same as your gaming computer, I ensure you that NOTHING will get done. That's just from personal experience.
To address the games exclusive to console: I don't feel like that's going to be as important, seeing as there will still be a market for Console Gaming for at least a decade. However, it's not difficult for the companies to change their controls over to PC format. They just need to get off their ass and they can get it in 2 weeks tops. Also, there are hundreds of non-console games specifically for PC. This includes crummy stuff like Maplestory and good stuff like FTL.
