What's the future for PC gaming?

The marketplace makes or breaks and the PC gaming platform is struggling according to some reports I've read. Consoles are hardwired and are upgraded every three years or so, but the PC keeps marching forward every half year. Gabe Newell was so upset with the "walled in" nature of Windows 8 that Steam is now porting games to Linux, so all hope isn't lost. Now there's talk of "BGA," or soldered-in CPU's for future motherboards. I upgrade my PC as I can afford to, but I feel like I'm driving on a highway that's steadily narrowing and choking. In light of these rumblings would I be stupid to continue upgrading my PC by migrating to Intel's Haswel and a pair of Radeon 8970's? What do you see in your crystal ball? Thank you.

Windows 8 Pro 64 bit OS
AMD Phenom II 965 CPU

55+ games on Steam

PC's are a major force in gaming. Who knows after the next-gen consoles are out. But at least the past couple of years, the best versions of the games usually were the PC ones.

Gabe Newell is just scared that the Steam marketplace will get eclipsed by the Windows Store which I think is silly to think that because there's tons to love for Steam. And people go where the best deals are and Steam brings it often enough. Newell/Valve wants their 30% cut of that software sale on Steam. If you buy the game in another marketplace, that's revenue lost. Everybody wants that 30% cut. Microsoft wants it. Steam wants it. Origin wants it. Ubisoft wants it. Apple wants it. Google wants it.

Right now, the various marketplaces are vying for exclusive titles and probably paying for that exclusivity. But like with anything, the money is on crossplatform titles so I bet you'll see the same titles across both Windows Store, Steam and other marketplaces. Microsoft is counting on the idea that you want your game achievements to be tallied with your Xbox achievements. Similarly, Steam is betting that you'll want to keep adding to your Steam achievements.

As gamers, it's better to focus on the games. There are no saints in business.
