Wow Bob, can't disagree more. Let's see here:
1) Motion controls are a useless argument. Kinect is already being developed for the PC. And unlike consoles, PC will have the option of developing extra harware (not to mention the wide, WIDE array of custom software) to work better with that little piece of motion goodness
2) FPS on a console over a PC is just too silly to make a serious argument about. Yes, you can stick a mouse into it, but that doesn't change the fact the developer is going to design a game for a console with a controller in mind (just like a developer isn't going to design a game for a PC with a 6-button mouse in mind). Which will still lead to there being auto-aim and all the other stuff that generally goes with a console FPS.
3) Intel's push into simplifying hardware (seen them new i7's with a graphic processor?) will take console's edge of "you need to buy and think about less shit". While I'm massively sure it will initially fail, another company that happens to have a graphics processor company under it's wing now, is likely to come up with something pretty fucking awesome if they try the same concept. The existence of SLI and crossfire already make things easier though.
4) PC gaming has always pushed the boundaries of gaming. Consoles come with a limit, PC doesn't. Where a console says "this is good enough", a PC says "we can do better, just go buy better stuff". A death of PC gaming would mean being stuck in a world of sameyness and I'm pretty sure that's not something the developers would be happy about.
And no, reaching the peak of graphic possibilities (which you might be right on) does not erase this concern. There's a LOT of headway to be made to make games more immersive, the AI probably being the biggest target. And programming mobs so they can appear completely realistic takes some serious processing power.
In fact, if the industry DOES focus on AI the way it focuses on graphics now (something Bethesda has been saying should be done since Oblivion and we might be nearing that point slowly)... boy oh boy. Well you might just be targeting the wrong platform with the "it's dead" speech. Lowering the graphics so they can run on a console is a piece of cake. Lowering the AI - yeah, good luck with that
5) Are you actually saying computers aren't there in people's homes? Cause if you are, say hi to Glornak, I haven't seen him since my last visit to Mars. I don't remember the last time I walked into a house that didn't have a PC. In fact, most people nowadays have some 2-3 PCs and several laptops to boot.
6) Point and click died ages ago. While it's a dear memory (a dear, dear, DEAR memory, I've recently gotten my hands on the Siberya games), it's not honestly something you can showcase and say "this is here, therefore here is now/future". Actually, you remember WHEN point and click games were being made? About the same time 2D titles with 3D stamps were being made. You know, that thing you can run on a graphic calculator right now. The fact point and click games are appearing on a console just shows the lack of power of said console. And are we even surprised considering we're talking about the wii?
Plenty more arguments, but my post is getting long enough as it is. Suffice to say, not really impressed by this week's show as making such a sweeping statement and backing it up so weakly is really... meh.
Do note - gaming IS spreading. It's spreading everywhere. Consoles, motion control, phones, browser, everywhere. But gaming spreading doesn't mean gaming in one place is dying. At best, it might be losing population somewhat as more possibilities open (and even that's a questionable fact), but that's a far cry from saying it's dying.
