I agree for the most part. 
 
3D doesn't really make sense until they can perfect autostereoscopy. I also think that 3D should extend "back" rather than "forward".  
 
In addition, I believe that the hardware in terms of games simply isn't enough right  now. Even though games like Metro 2033 support 3D natively, we'll still need to wait 4 years or more before games like that can be played with perfect performance at their highest settings even at 2D-settings, let alone 3D which will require more than double the framerate output. Your 5-10 year estimate seems fairly accurate to me. 

I was browsing Tested.com and noticed an article about how Sony thinks gaming will sell you on 3D at home or something, so I had to drop my two cents. But it turns out I ramble when I'm drunk... so I figured I'd post it here as my first submission to the Giantbomb Drunken Bloggers Association Xtreme. Enjoy, you miserable twat falafels =D
 
Of all forms of media, the interactive kind (currently known almost exclusively as "gaming"), will be the one that offers the killer app that will show you how great stereoscopy can be (aka "dual instrument for viewing," the actual name for 3D; NOT to be confused with the misnomer for the glasses method). 
 
I mean anybody with two eyes can tell you that using both is better than using just one for general everyday tasks. Sure for some gaming situations, particularly the aiming kind, monoscopy would serve the purpose better. But luckily we have an awesome appendage known as an eyelid that allows us to close off the vision of either or both of our two eyes at a time; a technique commonly practiced by virtually all sharpshooters. However If you're the type that thinks the technology to offer us an individual image for both of our eyes will fade out into oblivion, then you should probably pluck one of your eyes out right here and now upon reading this, because you've obviously never thought about using it in the first place.
 
Sure, the glasses method will largely die out. But just think about how many people use headphones nowadays. It's the same type of thing. In the 60's when headphones where fresh and newly available for consumer use, the actual implementation of tonal range and psycho-acoustics were pathetic at best. Just analogize that with color range and focal convergence of today's glasses methods and you will be able to picture a future of ironed out kinks.
 
And that's not to mention the many glasses-free technologies ranging from layered screens to multiple facing cameras calculating viewing angles. Optimally we will have tech that can track our eyes and determining where we are trying to focus and converge the content automatically while adding the appropriate focal depth blur. I could only predict those being largely part of head-mounted devices such as glasses.
 
Speaking of focal depth blur, it looks fine in 2D in games where your eyes are zeroes in on the crosshair which is glued to the middle of the screen. When developers expect you're using this they can add perhipheral effects like motion and focal blurs to make the experience more immersive. But when using 3D or actual 1:1 aiming methods (NOT to be confused with the so-called 1:1 PS Move implementations as seen in Killzone 3 which are more akin to mouse-like "feeling around" to line up the crosshair which is still stuck to the center of the screen) these become more like distractions since the software can't tell how deep within the scene you're trying to focus because the hardware can't tell where your eyes are looking.
 
When the depth blur is incorrect, or the left/right sync is off, or a number of other factors, these add to the total amount of visual fatigue one can endure. Much like the relatoinship between psycho-acoustics and audio fatigue commonly experienced with headphone use. For example when gaming with a bassy pair of headphones and an explosion goes off a few yards directly to your right, and you don't hear anything at all in your left ear: that makes my brain say, "What the fuck is happening? This isn't right one bit. I'm trying to tune my other ear to hear the non-existent acoustics and reverb, but all that does is gives me a headache!" 
 
 
I lost track of my point about needing further eye tracking technology to make it work right somewhere in there. All I'm saying is that even the concept of taking stereoscopic media seriously is still in its infancy. Wait 5 to 10 years for shit to get real at an affordable price. Technology will advance, believe it or not. Remember Laserdiscs? What a joke those were, amirite? BBL, gonna watch Slumdog Millionaire on Blu-Ray.
