Wishful thinking? Because people love messing with drivers, patches, updates and DRM on friday evening, while their beer is getting hot, trying to play their latest game on their PC with a small 22-24" screen, when they could just load the disc in their console and play it after a few minutes (in HD) on their 42" lcd/plasma with full surround. An entertainment system they also, already use for their movies. That's the simple reason why console gaming is growing while the inherent problems of PC gaming gets it pushed into oblivion. Think outside your box.
You seem to know nothing about what you're talking about so lets go at it one point at a time;
Drivers, patches, udpates; These exist in consoles too, or are you not playing current gen systems? PC/Mac drivers aren't even released often, as a heavy PC gamer I get an update what? Every 4-6 months?
DRM; Some games have it, most don't. I only play Steam games so the only DRM I'm presented with is built in and doesn't impact playing games at all.
Monitor vs TV; The problem with this being the control setup. I'd take my 20" monitor over my 42" Bravia any day of the week because of the superior controls on a PC. A PC also has
much more customisation. Off the top of my head; any resolution your monitor and graphics card can handle, better graphics, more control options, ability mod games, games cost less, ability to play online for free (though the Wii and PS3 do this too), mostly free DLC, run your own servers. It's just a much more customisable experience in general.
PC gaming is being pushed to oblivion; no. It's not. I work in the game development industry, I'm not some armchair pundit talking out my arse

.
Go to the local Best Buy and see how much shelf space has disappeared in the past six months in terms of both application and video game software for PC and then you tell me that PC gaming isn't in decline. And when you tell me that, I'll tell you I also was able to buy brand new software for my Atari 1040ST at that same Best Buy recently.
So lets stop banging on about PC gaming dying. The entire market is changing, yes I look around my game shops (GAME, GameStation, HMV) and there are still plenty of PC games there. Nothing has changed in them since I started visiting them in the late 90's. Steam and other digital distribution methods are changing gaming as there are
20 million+ people buying games from such methods.
Infact (
http://vgchartz.com) Console gaming isn't doing that much better than last gen (barring the Wii). It's just people get confused since games are being far more publicised to make up for the development costs of this generation than before.
